color blind? no?

so last night i went to the spurs game...yup! fun times! and they were playing the sacramento kings...whose jerseys are clearly purple right....clearly.....

purple right? right! but when you look on the jumbotron or the TV they look BLUE! like dark dark blue! a completely different color! hahaha it was freaking me out all game! okay so ive never watched the kings on TV but I kept wondering if the Lakers ever have this same problem and if purple is the color they want to be why don't they choose a pigment that doesn't appear BLUE on TV?....idk....it was fun game though!
