go to https://coolors.co/generate and go to Create a Palette Take two of the random colors and make them white (FFFFFF) lock the two white tiles (hover over them and click the lock.) press space 3 times, and the colors left you work with. Black doesn´t have to be one of them, its good for outlining. Make four types of art muted colors Pastels Neons and Dark colors if you want the extra challenge, you can try an extra style along with the palette enjoy!
