RE: GZG Colours

Or, they can "fly the colors" and change them for "parade" occasions. 
So
they would be blue with pink polka-dots for parade days and then a
camoflauged color for battle.

Or they can change color like squids and octopi and use this ability
like
signal flags of yore.

Come to think of it, while the color changes CAN be camoflage,
occasionally
they can indicate emotional states. I seem to recall some cephalopods
flashing colors when stimulated. This could be warning behaviour
(emotional
semiphores), or might be autonomic.

Paint 'em as you like, I'll PSB 'em into existance. ;->=
