Reading Your Shapes
Also, in regards to lighting, warm colors advance and cool colors recede. In this image of an operating room, the blue light on the operating table would be the first thing the eye goes to because it’s the brightest, but immediately the eye is drawn towards the door where the warm light is. So, if you want to draw the eye towards something you might be better off using a warm light. An interesting note is that this principle is used a lot in interior design. If they want a room the feel larger they paint it with a cool color like blue or green. A room can feel more intimate and smaller by painting it a warm color like red or orange.
When lighting a scene, don’t be afraid to put lights in areas without a visible light source. Many would think that this is cheating, but in reality it works well in being able to enhance the composition by leading the eye to specific parts of the scene. Again, returning to the operating room scene, I lightmapped it externally and put inside Unity3d. If you look closely, the lighting doesn’t quite match up to the light sources, but for the sake of composition and where we wanted to lead the player this works well.
