Fixed t condition.



MIT Licensed .Net library that makes converting between color spaces and comparing colors easy.

Getting Started

ColorMine is available as a nuget package so you can install by searching for "ColorMine" in the "Manage Nuget Packages" menu, or run the following command in the Package Manager Console:

PM> Install-Package ColorMine

Color Conversions

You can convert between any supported color spaces via generic methods like so:

var myRgb = new Rgb { R = 149, G = 13, B = 12 }
var myCmy = myRgb.To<Cmy>();
var myXyz = new Xyz { X = .44, Y = .7, Z = .99 }
var myLab = myXyz.To<Lab>();
var myYxy = new Xyz { Y1 = .1124, X = .22, Y2 = .14 }
var myHsl = myYxy.To<Hsl>();

Cmyk conversion also supports profiles

var myCmyk = myRgb
var myHunterLab = myCmyk

Online example at http://colormine.org/color-converter


Delta-E calculations take and compare colors in any of the supported formats.


double deltaE = myRgb.Compare(myCmy,new Cie1976Comparison());


double deltaE = myXyz.Compare(myLab,new CmcComparison(lightness: 2, chroma: 1));


double deltaE = myYxy.Compare(myHsl,new Cie94(Cie94Comparison.Application.GraphicArts));


double deltaE = myHunterLab.Compare(myLuv, new CieDe2000());

Huge thanks to Jonathan Hofinger for correct implementation of CieDe2000 and to Gaurav Sharma for test data.

Note: Delta-e calculations are quasimetric, the result of comparing color a to b isn't always equal to comparing color b to a...but it will probably be pretty close!
