The hue represented in light reflected in the opposite surfaces to those facing the sun or moon.
The surfaces of a
BasePart influenced by ColorShift_Bottom depends on the position and orientation of the
BasePart relative to the sun or moon’s position. Where the sun is directly overhead a
BasePart, the shift in color will only apply to the bottom surface.
This effect can be increased or reduced by altering
ColorShift_Bottom influences the opposite surfaces to
Lighting/ColorShift_Top. For a visual demonstration of this, please see the image below.
Lighting/ColorShift_Top and ColorShift_Bottom will interact with the
Lighting/OutdoorAmbient properties if they are greater than 0, 0, 0. Also, the influence of ColorShift_Bottom can be very hard to identify when
Lighting/GlobalShadows is enabled (as it is by default).
