My favorite palette was so messy that I had to clean it up. It seemed like a good time to take and post a picture of it. It is aluminum and is enameled white on the inside and black on the outside. The paints are protected when it is folded and closed. I like this palette because it has all my favorite colors and I can take it to workshops, use it for plein air painting, and use it at home. It's great for sketching, too. The thumb hole is great, especially for plein air. It folds out and is very comfortable because there is a rest for the thumb. Colors can be added for temporary use, such as the cobalt blue near the thumb hole now. My colors in the palette most of the time are burnt sienna, quinacradone gold, yellow ochre, hansa yellow, aurelian, alizarin, winsor red, magenta, cerulean, french ultramarine, pthalo blue, veridian, and sap green.
