I've never used the pen tool in Scratch before, but I've seen so many interesting projects during Getting Unstuck that used it that I knew I had to try it at some point during these 10 days. When the "touching color" prompt came up today, I thought about combining touching colors with the pen tool, and this was the result! Color palette was created by me.
