Painting Greens
I do use tube greens. Straight from the tube, they may look too strong… unnatural. With a bit of tweaking though, by mixing them with other colors on your palette, you can produce more natural looking greens. Tube greens are very convenient and can be great additions to your palette.
My base greens are sap green and phthalo green but I alter it by adding colors from my flower palette. You can see this in my first layer for the leaves.
Some favorite colors for mixing with phthalo and sap green are Anthraquinoid red and Carbazole violet. Anthraquinoid red and phthalo green make a vibrant black. Carbazole violet and greens make beautiful dark browns.
Neutral black is a good black also. It can be used to darken the greens without altering the temperature.
