Next Fish - Advice Please

[gregzz4]

George (gridley) I may be wrong, but I understand the only differences in Kole Tangs is in the body patterns, and I can't even find images of ones different than mine from Hawaii
A true Kole tang ( Ctenochaetus strigosus ) is a copper/brown color
What I see on the web as 'blue-looking' Koles are just lighting differences

Maybe someone can elaborate if I'm incorrect
