Character customization menu using a custom model

[storm depot]

Hey! I've been searching literally everywhere for something but literally nowhere says this
If i wanted to make a customization menu for a roleplay game or whatever, how would I make a menu that allows for paint brush editing? (I'm very new to scripting dont blame me if its super obvious 😭)

Like clicking on a part of the model to change the color of it kind of?

I'd look up an example but my laptop refuses to work rn ughh
