Redirect based on visitor color settings?

Has anyone seen a script for a redirect based on the visitors screen colour settings? and if so please would you let me have it. I've searched forums and archives across the globe today, but dont find a color based redirect.

e.g.
if color settings 32 bit do nothing
if color settings 16 bit go to URL
if color settings 256 colors got o another URL

I tried to modify a screen size redirect script...bad move

thanks a ton
