I have been experimenting with the color palette. First I started opening photos of paintings and using the eye dropper tool to select colors and then added them to the palette. Second I selected a base color the modified it by gradients and added them to the palette. I also increased the number of columns and rearranged the colors. It makes it a lot easier to paint. One needs only click on a color. Here’s a pic of the modified palette:
Maybe this is a common practice that everyone knows about, but I just came across it and thought it was worth bringing up.
