Creating custom themes for Aseprite

Hello! :wave:
Recently I wanted to try making a custom theme for Aseprite but I don’t know how to make one and if there is a template to use as a reference or to edit (I did found some UI sprite sheet in Aseprite’s folders)
So if anyone knows how to make a custom theme please tell me it would really help me, thank you :smile:

I’m also interested in thisss, nobody knows? :'c
