I use these macros for generating color:

.de CL
\\X'PS \\$1 \\$2 \\$3 setrgbcolor'\\c
..
.de BK
\\X'PS 0 0 0 setrgbcolor'\\c
..
.de EM
\\$3\\X'PS 1 0 0 setrgbcolor'\\$1\\X'PS 0 0 0 setrgbcolor'\\$2
..

They only work if you generate postscript (you can, of course, turn that
into pdf as well).
.CL r g b
sets the color to the rgb values (0 0 0 being black, 1 1 1 being white,
0.5 0.5 0.5 being middle grey)
.BK
sets the color to black.
.EM "string1" "string2" "string3"
(emphasis), where strings 2 and 3 are optional prints string3 in the current
color, followed by string1 in red and string2 in black (with no space between
strings 3, 1 and 2 — they work as .B or .I in the .ms macro package.
