Hi, I decided to paint a still life, it has been a while since I painted one. I tried to pre-mix colors, something I have been wanting to try. Kind of worked, pre-mixed some and mixed others as I went. I do see the advantage to pre-mixing, probably keeps you from playing around in your painting too much and graying down your colors. I set this up in a box, small silver tray, silver cream pitcher and a pear. This is oil on a 8 X 10 canvas panel.
