## Discussion

Discussion When applied to an NSBox object, this color supports Desktop Tinting in Dark Mode. With Desktop Tinting, the system modifies this color dynamically by incorporating some of the color from the underlying desktop image. The system does not apply this dynamic tinting effect to other types of views.
