Is there a Built-in function to obtain color coordinates from a color directive? I'm currently doing it the hard way:
colors = {RGBColor["AliceBlue"], RGBColor["DarkMagenta"]};
colorcoords =
ToExpression[
StringSplit[
StringSplit[StringSplit[ToString[InputForm[#]], "["][[2]],
"]"][[1]], ","]] & /@ colors
...
{{0.941176, 0.972549, 1.}, {0.545098, 0., 0.545098}}
