Not really, but for a simple version you could define macros for the 
color values you want, and then use these within the color \special. 
E.g.,

	\def\myredcolor{rgb 0.8 0.0 0.0}
	\def\mydarkcyancolor{cmyk 1.0 0.0 0.0 0.5}

	Some text... \special{color \myredcolor} ...red text...
	\special{color \mydarkcyancolor} ...cyan text...

I suppose you could even have a macro that accepts a tint parameter and 
calculates appropriate rgb or cmyk values.... left as an exercise for 
the reader.... :)
