Ya I’ve done that where one asset is way more detailed or just completely different colors than the rest! So I have something that may be helpful! My husband and I are trying to create a platform to help game developers and studios stay organized! One thing we have that I think would be perfect for you is that when you have a task open to create an asset you can put your color palette and any pictures you’re using as a reference right into your ticket! Would you be up to taking a look at it?
