TART?!?!?! <smooch> Shampoo kill you now!!

Purple? This has been racking my brains out for 
some time. Her hair is obviously blue. A light 
blue. A beautiful light blue. Not Purple. 
Barney is PURPLE! Purple does not define 
Shampoo's hair color.

Why does some people call her hair blue?

I hope you can open this binhexed pic I have included.
View it and tell me her hair color!
