Smelly Belly Recolours

I'm recolouring Smelly Belly as well to see if any colour schemes work for him. He is an E. coli, which are generally "pink" under the microscope (based on classification methods/gram stain) but if I limited myself to that all of my bacteria would be pink or purple. Because of this, I tried various colour schemes although I still do like the pink (or yellow-pink haha)
