Make a study of a high contrast image in which you allow the darks to have a noticeable color. Base the color on the palette you have used elsewhere in the picture rather than the photograph. It's up to you. If you have time, try another version, using a different color as the link to the darks.
Photos often make the large dark areas devoid of information, which we accept as reasonable because it's a photo. But that is not what the real scene looked like. If we were there, we would have been able to see all kinds of variation within that area. In a painting, a big chunk of territory with nothing going on, dark or light, usually feels blank and uninteresting. Look again at Mary Whyte's background. It's all dark, and all soft-edged, but there's a lot happening.
