Re: Black and white oil painting
Don't be afraid to actually use black, if you have it! Or, you can continue by mixing to black.
Depending on which pigment black you use (and perhaps which white), a mix of black and white may be a slightly bluish gray. This is easily fixed by adding a suitable earth color.
Based on traditional (film) and digital photographs, I have noticed that my own perception as to whether a gray is warm or cool, depends on the lightness of the gray. I see darker grays as warm, and lighter grays as cool. Your perception may differ. This is probably the opposite of what is desirable in painting, where we would expect darks to be cooler than lights. So, you may have to add a variable amount of earth color, depending on light or dark gray.
The trouble with mixed blacks based on red + green, is that slight variations make the result lean red or green. This is probably not desirable, for most compositions. Better to stick with blue and an earth color, because deviations to blue or earth will look more natural.
