Colors are mysterious things, they appear differently on different 
equipment, and people's eyes react differently to the same colors. I make a 
beautiful and instructive PowerPoint slide, but it looks completely 
different when projected for an audience.

May I suggest that colors should be used sparingly and that it could be a 
good idea to limit its use to the "Browser safe" colors: "The Browser-Safe 
Palette only contains 216 colors out of a possible 256. That is because the 
remaining 40 colors vary on Macs and PCs. By eliminating the 40 variable 
colors, this palette is optimized for cross-platform use."
