Yes you can use the paint. You may find the depth of hue to be less so you may layer colors or add more paint. I don’t often clean my palette until the hues get muddy or I need space. I try to place my colors near colors I may want to mix. I might put yellow or orange near greens, for example, so they are close for mixing. That way I get a variety of greens in my painting. Sometimes a mix gets a gray hue that’s great for shadows. Have fun mixing and reusing your palette paints. Theresa
