In the decorations layer there are colors on the bottom that you can choose from. I think that it should be a pallette that you can save colors to. It would be very helpful for art.
@jjbagley(View Post) Color 3*3 pixel blocks of diamond, and save the diamond palletes to your stamps. Example: https://powdertoy.co.uk/Browse/View.html?ID=769363 Stoopid image doesn't come up very big, unless I increase width which inversely expands height...but that makes the page laggy and hard to load when opening.
