Property Value

This property uses the color (Color property) of the object to calculate the light color for the bevel in percentages.

If set to 0, the same color as the color object is used. When a positive value is set, a brighter color is used, and when a negative value is set, a color darker than the background color is used.

This property can be used with the Darkness property to make detailed adjustments to the brightness of the bevel color.
