When I change the order of loading it doesn't work either and I get a 
different Postscript error (/undefined in rgb):

\input color
\input pstricks
\color{red} red text
\psline[linecolor=red](1,1)(3,3)
\bye

-> Error: /stackunderflow in --setrgbcolor--

\input pstricks
\input color
\color{red} red text
\psline[linecolor=red](1,1)(3,3)
\bye

-> Error: /undefined in rgb
