I just noticed today while on the boat that the hand full of tsunami sand eels that I threw in with my gulp have all now gone clear. They look like rainfish now
I should have clarified:
Even though the stuff gets darker, it don't do nothing bad to them GULPY things. 
Seriously though, bleeding of colored baits made of plastisol (which is what most soft plastic baits are made from) is pretty common. Colors like chartreuse, red and purple tend to bleed the most when mixed. But, I have never had a problem with the colors on Gulp! baits bleeding or blending with each other.
Thanks for bringing that down to a level we can all understand Bob
