Green, but the gray one's awesome too.

@ilikedonuts: I can understand your reason to like it .

Green pops from the pages more than gray.

@amratheking: And That My Man Is Correct !

Its gotta be green......!!!

@bezza: like I said that's correct .

Green: I grew up with Hulk being green and it's also my favorite color.

@aronmorales: that's nice .

@kazuma14: Why thank you.

Purple... naw, green.

Green is not a creative color

Which kinds of gray and green are we talking about here?

Green, the incest, shirtless hunk, impotent hunk, or omnipotent hunk variety?

Gray, the tuxedo variety, the shirtless hunk, the spiky dc version that's not so hunky or....?

Red, the PIS variety?

OP needs to be more specific.

@jeansummers: Why ?

@kazuma14: it's from a YouTube video you don't Wanna look it up

Captain Universe Blue...

@jeansummers: I see , well thanks for telling me .

@sodamyat: and that makes good sense .
