actually there are ...
in mkii btex/etex pipes to an external instance of tex and then converts
the dvi to mp code; so, there we have a mp picture that we can color as
such (color info done in the tex job is lost)
in mkiv btex/etex pipes to the current tex instance and mp never sees
the result, only dimensions, and as such there is nothing to color; if i
construct a more comples model for extensions i can make that work, but
i'd rather wait for mplib to be extended with multiple pre/postscripts
(is on the agenda but with low priority)

well, just define a color on the spot ..
{\definecolor[temp][specs]\color[temp]text}

indeed (althouh in mkiv they are the same .. btex/etex is converted to
textext on the fly)
