A feature request: Select additional colors of the Pointillism brush

Tags: #<Tag:0x00007fadf9139f58>

Currently, you can select only the main color of the Pointillism brush, other colors can not be affected by the user and are always derived from your primary color. It would be nice to have a better color menu for this brush where you would be able to pick 2 or 3 other colors in addition to your main color.
