Hanging in the Light or the Dark?

"Midnight Edge," the painting below, has brought up an interesting question: What is the best light for a piece of art to be viewed in? This piece actually looks best in a poorly lit room. The dark recedes while the light grays and red pop forward, increasing the sense of movement and excitement. In a well-lit room the contrast is defused. This diminishes the sense of drama and makes the painting more of a design exercise.
