Does the wine on the right look more red in person, too? I never would have thought a green base would do that.
The wine on the right is more red. On the left since I painted directly on white (of the paper) and since my red, alizarin crimson, is on the transparent side I mixed it with blue and cadmium red to get that deeper color (otherwise it would be too pinkish). On the right side, I didn't mix the bulk of the wine color part with anything, just straight alizarin. Glazing over green can have that effect, giving a rather transparent red a bright richness in both its darks and lights, giving it more depth. On the next post, the single wine glass, I did add blue to my alizarin that I painted over the green underpainting because I wanted the wine to be darker, but looking back at my study I kind of like it more red!
