If you want tons of personality, attitude, and exuberance I have a 4lb little grey guy with tons of Linustude, he may be little but he's a lion in his own mind.
Add to that two very lovable grey/white tuxedo kitties that personally invented tuxedotude and could stare down any human I know...
Seriously though I don't know if color has much to do with it, only certain breeds have certain traits....and most breeds have distintive colors, or color combo's.
