When I painted in acrylic, I used a deviled egg tray with a snap lid for the paints. By putting the different colors in the trays and using the snap lid, it keeps the acrylic colors moist, although occasionally it is good to spray the paint with a mixture mainly of water and a little flow aid. The snap lid serves as the pallet. You can occasionally peel off or wash off the colors on the palette. With this system and 2 coffee cans of water (one to keep the used brushes wet and one for cleaning the brushes), the start up and clean up is fast and easy. A good Deviled Egg Day.
