So Why is it Important to Understand the Color Bias of Blue?
1. When you are wanting to create a sense of depth in your painting, we know that warm colors come forward and cool colors go back. Within the subset of warms and cools, for example, if you are painting red flowers, you want to use warm-reds for those flowers or petals that you want to be in the foreground or to come toward the viewer. Subsequently, you would use your blue-reds or ‘cool’ reds for those you want to push back.
