I’m an artist who works mostly digitally. When I am mixing colors I have the color dialog right there on the screen next to the art, with my changes being reflected live. How does this color work with the rest of the work? That’s what’s important.

The only reason traditional artists use a palette far away from their art for their paint is because that works in the physical world. Mixing my colors right next to my virtual canvas is a huge speed-up compared to painting a ton of thumbnails with different colors.
