Im partial to a nice purple, its a weird colour not often looked at, just like my correct spelling of the word colour here!
however for the overkill amoung us, why not transittion effect from light blue through to purple the more it hits the bottom of the tank....hmmmm?
If you look close enough - You can just see me over there on the far bottom left stalking my prey with my spear gun to take down that gropper for dinner...muhahahaha*cough*haha
