small feature request: color palette and picker for pen tool

It would be cool to have more colors than the 10~ given for the pen tool.

There’s a color palette feature for notes, and there used(?) to be a color picker feature as well (https://www.youtube.com/watch?v=GnIg6-R8Lck).

It would be useful for me as an artist to make annotations about art references I have saved.
