I just took a photograph of a real painting at home and tried to produce a brush from it.
RGBA was actually Ramon’s term, since he used that to describe his DAOil brushes even before I created the Lightness option. His brushtips actually were colored though, since you couldn’t choose your own color before the Lightness option existed. You just had to paint with an orange, blueish-green, or gray brush (those were the colors in his brushpack). My original purpose for Lightness mode was to make Color Stamp style brushes that you could change the color of, for quickly drawing large amounts of grass, leaves, etc, but when I saw Ramon’s DAOil brushes, I realized the mode would also allow the impasto effect he got with those to be used with any color, and that excited all the rest of the artists here
