You can animate color per vertex data applied to polygon vertices. For example, you can create an animation of blood color dripping down a wall or of a crystal changing from dull to glowing green.
You can quickly create history on a model by choosing Edit Mesh > Transform Component, but moving nothing.

Troubleshooting color per vertex animation
Playback becomes slow after animating vertex colors?
Maya creates animation curves for each vertex per face. For this reason, playback performance slows down significantly if you animate too many vertices.
Try to limit the number of vertices you animate. Another alternative is to delete the static animation curves.
I get a warning “Active objects have no keyable attributes?”
You must first apply a color. You cannot set a keyframe if there is no color assigned.
I get a warning “Current manipulator and active objects have no keyable attributes?”
You must add construction history to the mesh. If the mesh does not have construction history, the vertex color change not set a key.
You can quickly create history on a model by using Edit Mesh > Transform Component with translation set to 0.
