# [metapost] Problem with colors

If I use the following MP program, I get a red X exactly as I would expect. If I change red to any of cyan, magenta, or yellow, I get an error. I'm not entirely sure what I'm doing wrong.

If I change the \color{yellow} to \color[rgb]{1,1,0} then I can get yellow text. (Presumably, I can do the same with cyan or magenta, but I didn't test it.)

$cat foo.mp prologues := 3; outputtemplate := "%j.mps"; verbatimtex %&latex \documentclass{article} \usepackage{color} \begin{document} etex beginfig(1); label(btex \color{red}X etex, origin); endfig; end$ cat foo.log
