I make games. I love detail and I get lost in detail. -One such detail popped up during the development of [Memory Which Does Not Suck](https://github.com/lucasb-eyer/mwdns/), -when we wanted the server to assign the players random colors. Sometimes -two players got very similar colors, which bugged me. The very same evening, -[I want hue](http://tools.medialab.sciences-po.fr/iwanthue/) was the top post -on HackerNews' frontpage and showed me how to Do It Right™. Last but not -least, there was no library for handling color spaces available in go. Colorful -does just that and implements Go's `color.Color` interface. - -What? -===== -Go-Colorful stores colors in RGB and provides methods from converting these to various color-spaces. Currently supported colorspaces are: - -- **RGB:** All three of Red, Green and Blue in [0..1]. -- **HSL:** Hue in [0..360], Saturation and Luminance in [0..1]. For legacy reasons; please forget that it exists. -- **HSV:** Hue in [0..360], Saturation and Value in [0..1]. You're better off using HCL, see below. -- **Hex RGB:** The "internet" color format, as in #FF00FF. -- **Linear RGB:** See [gamma correct rendering](http://www.sjbrown.co.uk/2004/05/14/gamma-correct-rendering/). -- **CIE-XYZ:** CIE's standard color space, almost in [0..1]. -- **CIE-xyY:** encodes chromacity in x and y and luminance in Y, all in [0..1] -- **CIE-L\*a\*b\*:** A *perceptually uniform* color space, i.e. distances are meaningful. L\* in [0..1] and a\*, b\* almost in [-1..1]. -- **CIE-L\*u\*v\*:** Very similar to CIE-L\*a\*b\*, there is [no consensus](http://en.wikipedia.org/wiki/CIELUV#Historical_background) on which one is "better". -- **CIE-L\*C\*h° (HCL):** This is generally the [most useful](http://vis4.net/blog/posts/avoid-equidistant-hsv-colors/) one; CIE-L\*a\*b\* space in polar coordinates, i.e. a *better* HSV. H° is in [0..360], C\* almost in [-1..1] and L\* as in CIE-L\*a\*b\*. - -For the colorspaces where it makes sense (XYZ, Lab, Luv, HCl), the -[D65](http://en.wikipedia.org/wiki/Illuminant_D65) is used as reference white -by default but methods for using your own reference white are provided. - -A coordinate being *almost in* a range means that generally it is, but for very -bright colors and depending on the reference white, it might overflow this -range slightly. For example, C\* of #0000ff is 1.338. - -Unit-tests are provided. - -Nice, but what's it useful for? -------------------------------- - -- Converting color spaces. Some people like to do that. -- Blending (interpolating) between colors in a "natural" look by using the right colorspace. -- Generating random colors under some constraints (e.g. colors of the same shade, or shades of one color.) -- Generating gorgeous random palettes with distinct colors of a same temperature. - -What not (yet)? -=============== -There are a few features which are currently missing and might be useful. -I just haven't implemented them yet because I didn't have the need for it. -Pull requests welcome. - -- Sorting colors (potentially using above mentioned distances) - -So which colorspace should I use? -================================= -It depends on what you want to do. I think the folks from *I want hue* are -on-spot when they say that RGB fits to how *screens produce* color, CIE L\*a\*b\* -fits how *humans perceive* color and HCL fits how *humans think* colors. - -Whenever you'd use HSV, rather go for CIE-L\*C\*h°. for fixed lightness L\* and -chroma C\* values, the hue angle h° rotates through colors of the same -perceived brightness and intensity. - -How? -==== - -### Installing -Installing the library is as easy as - -```bash -$ go get github.com/lucasb-eyer/go-colorful -``` - -The package can then be used through an - -```go -import "github.com/lucasb-eyer/go-colorful" -``` - -### Basic usage - -Create a beautiful blue color using different source space: - -```go -// Any of the following should be the same -c := colorful.Color{0.313725, 0.478431, 0.721569} -c, err := colorful.Hex("#517AB8") -if err != nil{ - log.Fatal(err) -} -c = colorful.Hsv(216.0, 0.56, 0.722) -c = colorful.Xyz(0.189165, 0.190837, 0.480248) -c = colorful.Xyy(0.219895, 0.221839, 0.190837) -c = colorful.Lab(0.507850, 0.040585,-0.370945) -c = colorful.Luv(0.507849,-0.194172,-0.567924) -c = colorful.Hcl(276.2440, 0.373160, 0.507849) -fmt.Printf("RGB values: %v, %v, %v", c.R, c.G, c.B) -``` - -And then converting this color back into various color spaces: - -```go -hex := c.Hex() -h, s, v := c.Hsv() -x, y, z := c.Xyz() -x, y, Y := c.Xyy() -l, a, b := c.Lab() -l, u, v := c.Luv() -h, c, l := c.Hcl() -``` - -Note that, because of Go's unfortunate choice of requiring an initial uppercase, -the name of the functions relating to the xyY space are just off. If you have -any good suggestion, please open an issue. (I don't consider XyY good.) - -### The `color.Color` interface -Because a `colorful.Color` implements Go's `color.Color` interface (found in the -`image/color` package), it can be used anywhere that expects a `color.Color`. - -Furthermore, you can convert anything that implements the `color.Color` interface -into a `colorful.Color` using the `MakeColor` function: - -```go -c, ok := colorful.MakeColor(color.Gray16{12345}) -``` - -**Caveat:** Be aware that this latter conversion (using `MakeColor`) hits a -corner-case when alpha is exactly zero. Because `color.Color` uses pre-multiplied -alpha colors, this means the RGB values are lost (set to 0) and it's impossible -to recover them. In such a case `MakeColor` will return `false` as its second value. - -### Comparing colors -In the RGB color space, the Euclidian distance between colors *doesn't* correspond -to visual/perceptual distance. This means that two pairs of colors which have the -same distance in RGB space can look much further apart. This is fixed by the -CIE-L\*a\*b\*, CIE-L\*u\*v\* and CIE-L\*C\*h° color spaces. -Thus you should only compare colors in any of these space. -(Note that the distance in CIE-L\*a\*b\* and CIE-L\*C\*h° are the same, since it's the same space but in cylindrical coordinates) - -![Color distance comparison](doc/colordist/colordist.png) - -The two colors shown on the top look much more different than the two shown on -the bottom. Still, in RGB space, their distance is the same. -Here is a little example program which shows the distances between the top two -and bottom two colors in RGB, CIE-L\*a\*b\* and CIE-L\*u\*v\* space. You can find it in `doc/colordist/colordist.go`. - -```go -package main - -import "fmt" -import "github.com/lucasb-eyer/go-colorful" - -func main() { - c1a := colorful.Color{150.0/255.0, 10.0/255.0, 150.0/255.0} - c1b := colorful.Color{ 53.0/255.0, 10.0/255.0, 150.0/255.0} - c2a := colorful.Color{10.0/255.0, 150.0/255.0, 50.0/255.0} - c2b := colorful.Color{99.9/255.0, 150.0/255.0, 10.0/255.0} - - fmt.Printf("DistanceRgb: c1: %v\tand c2: %v\n", c1a.DistanceRgb(c1b), c2a.DistanceRgb(c2b)) - fmt.Printf("DistanceLab: c1: %v\tand c2: %v\n", c1a.DistanceLab(c1b), c2a.DistanceLab(c2b)) - fmt.Printf("DistanceLuv: c1: %v\tand c2: %v\n", c1a.DistanceLuv(c1b), c2a.DistanceLuv(c2b)) - fmt.Printf("DistanceCIE76: c1: %v\tand c2: %v\n", c1a.DistanceCIE76(c1b), c2a.DistanceCIE76(c2b)) - fmt.Printf("DistanceCIE94: c1: %v\tand c2: %v\n", c1a.DistanceCIE94(c1b), c2a.DistanceCIE94(c2b)) -} -``` - -Running the above program shows that you should always prefer any of the CIE distances: - -```bash -$ go run colordist.go -DistanceRgb: c1: 0.3803921568627451 and c2: 0.3858713931171159 -DistanceLab: c1: 0.3204845831279805 and c2: 0.2439715175856528 -DistanceLuv: c1: 0.5134369614199698 and c2: 0.25686928398606323 -DistanceCIE76: c1: 0.3204845831279805 and c2: 0.2439715175856528 -DistanceCIE94: c1: 0.19799168128511327 and c2: 0.12207136371167401 -``` - -It also shows that `DistanceLab` is more formally known as `DistanceCIE76` and -has been superseded by the slightly more accurate, but much more expensive -`DistanceCIE94`. - -Note that `AlmostEqualRgb` is provided mainly for (unit-)testing purposes. Use -it only if you really know what you're doing. It will eat your cat. - -### Blending colors -Blending is highly connected to distance, since it basically "walks through" the -colorspace thus, if the colorspace maps distances well, the walk is "smooth". - -Colorful comes with blending functions in RGB, HSV and any of the LAB spaces. -Of course, you'd rather want to use the blending functions of the LAB spaces since -these spaces map distances well but, just in case, here is an example showing -you how the blendings (`#fdffcc` to `#242a42`) are done in the various spaces: - -![Blending colors in different spaces.](doc/colorblend/colorblend.png) - -What you see is that HSV is really bad: it adds some green, which is not present -in the original colors at all! RGB is much better, but it stays light a little -too long. LUV and LAB both hit the right lightness but LAB has a little more -color. HCL works in the same vein as HSV (both cylindrical interpolations) but -it does it right in that there is no green appearing and the lighthness changes -in a linear manner. - -While this seems all good, you need to know one thing: When interpolating in any -of the CIE color spaces, you might get invalid RGB colors! This is important if -the starting and ending colors are user-input or random. An example of where this -happens is when blending between `#eeef61` and `#1e3140`: - -![Invalid RGB colors may crop up when blending in CIE spaces.](doc/colorblend/invalid.png) - -You can test whether a color is a valid RGB color by calling the `IsValid` method -and indeed, calling IsValid will return false for the redish colors on the bottom. -One way to "fix" this is to get a valid color close to the invalid one by calling -`Clamped`, which always returns a nearby valid color. Doing this, we get the -following result, which is satisfactory: - -![Fixing invalid RGB colors by clamping them to the valid range.](doc/colorblend/clamped.png) - -The following is the code creating the above three images; it can be found in `doc/colorblend/colorblend.go` - -```go -package main - -import "fmt" -import "github.com/lucasb-eyer/go-colorful" -import "image" -import "image/draw" -import "image/png" -import "os" - -func main() { - blocks := 10 - blockw := 40 - img := image.NewRGBA(image.Rect(0,0,blocks*blockw,200)) - - c1, _ := colorful.Hex("#fdffcc") - c2, _ := colorful.Hex("#242a42") - - // Use these colors to get invalid RGB in the gradient. - //c1, _ := colorful.Hex("#EEEF61") - //c2, _ := colorful.Hex("#1E3140") - - for i := 0 ; i < blocks ; i++ { - draw.Draw(img, image.Rect(i*blockw, 0,(i+1)*blockw, 40), &image.Uniform{c1.BlendHsv(c2, float64(i)/float64(blocks-1))}, image.ZP, draw.Src) - draw.Draw(img, image.Rect(i*blockw, 40,(i+1)*blockw, 80), &image.Uniform{c1.BlendLuv(c2, float64(i)/float64(blocks-1))}, image.ZP, draw.Src) - draw.Draw(img, image.Rect(i*blockw, 80,(i+1)*blockw,120), &image.Uniform{c1.BlendRgb(c2, float64(i)/float64(blocks-1))}, image.ZP, draw.Src) - draw.Draw(img, image.Rect(i*blockw,120,(i+1)*blockw,160), &image.Uniform{c1.BlendLab(c2, float64(i)/float64(blocks-1))}, image.ZP, draw.Src) - draw.Draw(img, image.Rect(i*blockw,160,(i+1)*blockw,200), &image.Uniform{c1.BlendHcl(c2, float64(i)/float64(blocks-1))}, image.ZP, draw.Src) - - // This can be used to "fix" invalid colors in the gradient. - //draw.Draw(img, image.Rect(i*blockw,160,(i+1)*blockw,200), &image.Uniform{c1.BlendHcl(c2, float64(i)/float64(blocks-1)).Clamped()}, image.ZP, draw.Src) - } - - toimg, err := os.Create("colorblend.png") - if err != nil { - fmt.Printf("Error: %v", err) - return - } - defer toimg.Close() - - png.Encode(toimg, img) -} -``` - -#### Generating color gradients -A very common reason to blend colors is creating gradients. There is an example -program in [doc/gradientgen.go](doc/gradientgen/gradientgen.go); it doesn't use any API -which hasn't been used in the previous example code, so I won't bother pasting -the code in here. Just look at that gorgeous gradient it generated in HCL space: - -!["Spectral" colorbrewer gradient in HCL space.](doc/gradientgen/gradientgen.png) - -### Getting random colors -It is sometimes necessary to generate random colors. You could simply do this -on your own by generating colors with random values. By restricting the random -values to a range smaller than [0..1] and using a space such as CIE-H\*C\*l° or -HSV, you can generate both random shades of a color or random colors of a -lightness: - -```go -random_blue := colorful.Hcl(180.0+rand.Float64()*50.0, 0.2+rand.Float64()*0.8, 0.3+rand.Float64()*0.7) -random_dark := colorful.Hcl(rand.Float64()*360.0, rand.Float64(), rand.Float64()*0.4) -random_light := colorful.Hcl(rand.Float64()*360.0, rand.Float64(), 0.6+rand.Float64()*0.4) -``` - -Since getting random "warm" and "happy" colors is quite a common task, there -are some helper functions: - -```go -colorful.WarmColor() -colorful.HappyColor() -colorful.FastWarmColor() -colorful.FastHappyColor() -``` - -The ones prefixed by `Fast` are faster but less coherent since they use the HSV -space as opposed to the regular ones which use CIE-L\*C\*h° space. The -following picture shows the warm colors in the top two rows and happy colors -in the bottom two rows. Within these, the first is the regular one and the -second is the fast one. - -![Warm, fast warm, happy and fast happy random colors, respectively.](doc/colorgens/colorgens.png) - -Don't forget to initialize the random seed! You can see the code used for -generating this picture in `doc/colorgens/colorgens.go`. - -### Getting random palettes -As soon as you need to generate more than one random color, you probably want -them to be distinguishible. Playing against an opponent which has almost the -same blue as I do is not fun. This is where random palettes can help. - -These palettes are generated using an algorithm which ensures that all colors -on the palette are as distinguishible as possible. Again, there is a `Fast` -method which works in HSV and is less perceptually uniform and a non-`Fast` -method which works in CIE spaces. For more theory on `SoftPalette`, check out -[I want hue](http://tools.medialab.sciences-po.fr/iwanthue/theory.php). Yet -again, there is a `Happy` and a `Warm` version, which do what you expect, but -now there is an additional `Soft` version, which is more configurable: you can -give a constraint on the color space in order to get colors within a certain *feel*. - -Let's start with the simple methods first, all they take is the amount of -colors to generate, which could, for example, be the player count. They return -an array of `colorful.Color` objects: - -```go -pal1, err1 := colorful.WarmPalette(10) -pal2 := colorful.FastWarmPalette(10) -pal3, err3 := colorful.HappyPalette(10) -pal4 := colorful.FastHappyPalette(10) -pal5, err5 := colorful.SoftPalette(10) -``` - -Note that the non-fast methods *may* fail if you ask for way too many colors. -Let's move on to the advanced one, namely `SoftPaletteEx`. Besides the color -count, this function takes a `SoftPaletteSettings` object as argument. The -interesting part here is its `CheckColor` member, which is a boolean function -taking three floating points as arguments: `l`, `a` and `b`. This function -should return `true` for colors which lie within the region you want and `false` -otherwise. The other members are `Iteration`, which should be within [5..100] -where higher means slower but more exact palette, and `ManySamples` which you -should set to `true` in case your `CheckColor` constraint rejects a large part -of the color space. - -For example, to create a palette of 10 brownish colors, you'd call it like this: - -```go -func isbrowny(l, a, b float64) bool { - h, c, L := colorful.LabToHcl(l, a, b) - return 10.0 < h && h < 50.0 && 0.1 < c && c < 0.5 && L < 0.5 -} -// Since the above function is pretty restrictive, we set ManySamples to true. -brownies := colorful.SoftPaletteEx(10, colorful.SoftPaletteSettings{isbrowny, 50, true}) -``` - -The following picture shows the palettes generated by all of these methods -(sourcecode in `doc/palettegens/palettegens.go`), in the order they were presented, i.e. -from top to bottom: `Warm`, `FastWarm`, `Happy`, `FastHappy`, `Soft`, -`SoftEx(isbrowny)`. All of them contain some randomness, so YMMV. - -![All example palettes](doc/palettegens/palettegens.png) - -### Sorting colors -TODO: Sort using dist fn. - -### Using linear RGB for computations -There are two methods for transforming RGB<->Linear RGB: a fast and almost precise one, -and a slow and precise one. - -```go -r, g, b := colorful.Hex("#FF0000").FastLinearRgb() -``` - -TODO: describe some more. - -### Want to use some other reference point? - -```go -c := colorful.LabWhiteRef(0.507850, 0.040585,-0.370945, colorful.D50) -l, a, b := c.LabWhiteRef(colorful.D50) -``` - -### Reading and writing colors from databases - -The type `HexColor` makes it easy to store colors as strings in a database. It -implements the [https://godoc.org/database/sql#Scanner](database/sql.Scanner) -and [database/sql/driver.Value](https://godoc.org/database/sql/driver.Value) -interfaces which provide automatic type conversion. - -Example: - -```go -var hc HexColor -_, err := db.QueryRow("SELECT '#ff0000';").Scan(&hc) -// hc == HexColor{R: 1, G: 0, B: 0}; err == nil -``` - -FAQ -=== - -### Q: I get all f!@#ed up values! Your library sucks! -A: You probably provided values in the wrong range. For example, RGB values are -expected to reside between 0 and 1, *not* between 0 and 255. Normalize your colors. - -### Q: Lab/Luv/HCl seem broken! Your library sucks! -They look like this: - - - -A: You're likely trying to generate and display colors that can't be represented by RGB, -and thus monitors. When you're trying to convert, say, `HCL(190.0, 1.0, 1.0).RGB255()`, -you're asking for RGB values of `(-2105.254 300.680 286.185)`, which clearly don't exist, -and the `RGB255` function just casts these numbers to `uint8`, creating wrap-around and -what looks like a completely broken gradient. What you want to do, is either use more -reasonable values of colors which actually exist in RGB, or just `Clamp()` the resulting -color to its nearest existing one, living with the consequences: -`HCL(190.0, 1.0, 1.0).Clamp().RGB255()`. It will look something like this: - - - -[Here's an issue going in-depth about this](https://github.com/lucasb-eyer/go-colorful/issues/14), -as well as [my answer](https://github.com/lucasb-eyer/go-colorful/issues/14#issuecomment-324205385), -both with code and pretty pictures. Also note that this was somewhat covered above in the -["Blending colors" section](https://github.com/lucasb-eyer/go-colorful#blending-colors). - -### Q: In a tight loop, conversion to Lab/Luv/HCl/... are slooooow! -A: Yes, they are. -This library aims for correctness, readability, and modularity; it wasn't written with speed in mind. -A large part of the slowness comes from these conversions going through `LinearRgb` which uses powers. -I implemented a fast approximation to `LinearRgb` called `FastLinearRgb` by using Taylor approximations. -The approximation is roughly 5x faster and precise up to roughly 0.5%, -the major caveat being that if the input values are outside the range 0-1, accuracy drops dramatically. -You can use these in your conversions as follows: - -```go -col := // Get your color somehow -l, a, b := XyzToLab(LinearRgbToXyz(col.LinearRgb())) -``` - -If you need faster versions of `Distance*` and `Blend*` that make use of this fast approximation, -feel free to implement them and open a pull-request, I'll happily accept. - -The derivation of these functions can be followed in [this Jupyter notebook](doc/LinearRGB Approximations.ipynb). -Here's the main figure showing the approximation quality: - -![approximation quality](doc/approx-quality.png) - -More speed could be gained by using SIMD instructions in many places. -You can also get more speed for specific conversions by approximating the full conversion function, -but that is outside the scope of this library. -Thanks to [@ZirconiumX](https://github.com/ZirconiumX) for starting this investigation, -see [issue #18](https://github.com/lucasb-eyer/go-colorful/issues/18) for details. - -### Q: Why would `MakeColor` ever fail!? -A: `MakeColor` fails when the alpha channel is zero. In that case, the -conversion is undefined. See [issue 21](https://github.com/lucasb-eyer/go-colorful/issues/21) -as well as the short caveat note in the ["The `color.Color` interface"](README.md#the-colorcolor-interface) -section above. - -Who? -==== - -This library has been developed by Lucas Beyer with contributions from -Bastien Dejean (@baskerville), Phil Kulak (@pkulak) and Christian Muehlhaeuser (@muesli). - -Release Notes -============= - -### Version 1.0 -- API Breaking change in `MakeColor`: instead of `panic`ing when alpha is zero, it now returns a secondary, boolean return value indicating success.
