color

The color of the ambient occlusion. Recommended in scenes where bounced light has a uniform "color", for instance a scene that is predominantly lit by a blue sky. The color is expected to be in the sRGB color space, and is automatically converted to linear space for you. Keep the color pretty dark for sensible results.
