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

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>();

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

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

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));

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!
