Controls the lighting that will affect the color of the next object rendered by the Draw Engine. Each control register is specific to a draw-color. Thus, you can make patterns within surfaces appear to self illuminate, or react to different lights, etc. Note that you can set a bit in the first control register that will cause it to drive both colors identically. Note that you can configure the Lighting Engine to 'do nothing' to the input colors, by clearing the control register's USE_LIGHTING_ENGINE bit to use 'Self Lit' mode. Then, you can set the one or two material colors that you need, and draw objects using the Draw Engine. In this configuration, they will use the exact colors that you have specified.
