Feature request: Start with a few predefined colors like Red, Green and Blue. It's easier to try, and latter people can personalize it. Perhaps a discrete palette with ¿16? options is better, with the advanced option to pick the color like now or select a color like #ff8040.
Yeah, the initial experience with no colors doesn’t look great. I can implement this when I have some free time, if you feel like doing it please feel free to open a PR. Thanks!
