I'm waiting for the purple "emo" hulk. he gets stronger as he grows more depressed, but he fights like a sissy. He tries to cut himself, but grows more depressed (and more powerful) when the razor just shatters against his skin. 
 
in answer to the question, No. I don't even like having a red one.

Marvel already uses enough terrible ideas, don't try to add to them.  It's the Hulk, not a bag of M&M's.

Banner himself was the blue hulk shortly, in addition theres the one parodying the Red/Green hulk situation in the cute comics at the end of the issues.
Really though, A-Bomb already holds the title of being the " blue Hulk " in the family. I'm really still surprised with how well the Hulk stories have turned out,
so I can't poke fun here.

what color Hulks are there already anyway? I know there's green, red, and gray. Is there any color I'm missing?

Honestly i'm tired of seeing different color hulks.  
 
I don't see why his color and varying it ever became a major theme to his character.

You guys are late...

No.

They could make a pink Hulk. Instead of The Incredible Hulk he would be The Fabulous Hulk.

 
There should be a Hulk of this hue.
