Frame Change Colors [SOLVED]

Had a reply from zwift on Twitter, it’s been passed on and flagged after showing to pics 1month apart.
Maybe a fix incoming, didn’t know when they changed the colour slider to add pink?

June, 2021. Have been riding the Grey Everest bike for a while, and want to change its colour as it is dull.
Seems this is not an option, Why ?

Some bikes you can’t change the colour. The Trek Emonda is one of them.
