you gotta right click and override materials and right click and go to show in element viewer and go to materials

Thanks very much!
Just so you know, the reason i put this as a discussion is to make sure other beginners can find it where they need it. Sometimes you just don't want to spend time wading through video tutorials. Again, thanks very much, this helped restore my characters completely.

changing teamcolour works fine for me, but the spots and gradient dont change at all. Tried this with multiple hairstyles, same issue.

Is it possible to have the hairstyles be two coloured?

Here's my way:

Right click on the Inkling, next, Click on override materials, then, next, right click on the Inkling (Again), next, click on view element editor *Model*, next, click on the plus by materials, next, find the teamcolor (Not 2), next click on the color of the Inkling's hair, and finally, set it to what ever color you want, and that way, your Inkling model will have a different colored hair. But, if it does not work, it's easy. Just go back to the models, and right click on the Inkling, and click on model and try it again and again until it turns into the color you want.
