The color phenomenon that I want to talk about here is the relationship of blue and red, and how the pairing of blue and red can enhance a drawing.
In this figure drawing, there were two different light sources falling accross the figure. If I treated the light the same way on both sides of the figure, the figure would have appeared flat. By choosing to have a warm (red) side and a cool blue side, it adds dimension to the figure.
Red and blue have a jarring personality - take a bright true blue and place it next to a true red and your eye vibrates a little. The eye does not read red and blue in the same way, causing a vibration (this phenomenon always makes me think of 3D glasses). As artists we can use this to our advantage.
When you have a highlight, such as the one on her hand, you can make the white highlight "pop" a little by using a shade of red on one side and a shade of blue on the other.
Highlights will appear brighter if you use a warm color on one side and a cool color on the other.
Fellow artists - have you used red and blue with a purpose? Share your work and your technique! Post a comment and a link to your work!
