I think someone should try to morph a grey spider

They have, it's called an axanthic spider.

I have a "normal" female that gets paler and redder with every shed. She looked normal for her first two years of life and then started changing colors with every shed. This has been going on for the last 4-5 years and some of her daughters I held back 3 years ago are now starting to do the same thing.
