ok, good news first we can now use the graphics package now, its really cool

working on color people... just be patient

[math]\color{red}test[/math]

wait wait maybe its working

haha.... ok now how to use color, can someone please compile a list of colors with names for me in such format:

\definecolor{name}{model}{spec}

latex supports rgb, cmyk, hsv and hls color models.

already defined: white, yellow red, green, blue, magenta, cyan

example:

\definecolor{red}{rgb}{1, 0, 0}
