A brush to gently adjust the color of an area.
Sometimes I need a smaller color adjustment that can't be done with the power of painting over something (because I don't want to ruin my shading) or a new layer. It is a simple brush that is set to color mode. If set to normal, it can be used as a fluffy shading brush.

It isn't anything special, but it really does work in the specific situations like no other brush does. I hope it helps you guys out too. :)
