Found while shed hunting

Found this guy while out shed hunting, he was submerged in the creek in a section that the water isn’t moving. This is after a power wash. I have him back in a bucket for degreasing. I actually love these colors. Does anyone know if after macerating him if he’ll stay looking like this?

I’m at a loss what to do with him 😂

I usually do the boil, power wash, 40 volume whitening, but I can I skip all of that and just get him degreased and keep him looking like he does?
