You should try “rainbow city” :3 (SA in chap 3, best to skip but Mc so prettty)
Also I got list of ONLY THE PRETTIEST MUSHROOM HEADS https://www.mangago.me/home/mangalist/2903759/

But if you looking for exotic hair color try “my perfect enemy is finally broke” (he dyes it dark green a few chapters in and I love the art style)
