Gradients can be used to enhance and control texture maps.

Vertical Gradient Baking

The Dota2 Character Art Guide describes how to bake a vertical gradient into the diffuse, to emphasize depth and create focus.

Gradient Remapping

Gradient remapping is a method to replace the colors of a texture using 1D gradients, for more variation.
