If you want to organize your colors automatically, without switching them one by one, then auto organize is what you're looking for.
As soon as you tap it, you'll see a list of combinations you can choose.
One example is R, G, B. This means the colors will be organized from the one with the greatest Red to the one with the smallest Red. In case of a tie, from greatest Green to smallest Green, and again, in case of a tie, from greates Blue to smallest Blue.
Hu, S, L is usually the most useful.
Try them out, you might find one that pleases you!
