When you create a brush, using black as default, you should be able to have the ability to change colors to any color.

When you make a brush in Photoshop, you can change the color of the brush. Likewise, DP10 should allow this ability, especially when a color hasn't been specified in the intial creation of the brush.

You shouldn't have to make a custom brush for every color you intend to use. I shouldn't have to make a version of the same brush that's black and then another one that's white, and then another one that's gray, and another one that's red, etc.

You should be able to select any color from the color bar and the brush should take on that color, for either the line or the fill.

To have multiple versions of the same brush in the brush gallery that are only differentiated by color is inefficient, tedious and not beneficial in terms of workflow.
