How to edit color preference and change default palette size?

Thanks for make drawOnYourScreen works at Gnome 42. However, is there a way to change color instead of using default 9 color? And how to change default palette size?

Take a look at this #25. I think this is solved with v12.6. Sorry it took me so long. If thats not what you meant please reopen this issue.
