The defaults settings can be set from the Toolbox.

Brush Colors
This section of the palette contains two large overlapping squares - the one in front is the "Outline Color" (previously called foreground color), the one in back is the "Fill Color" (previously called background color). When you are creating a layer of only one color, the "Outline Color" is always used. When you create a region and an outline simultaneously, the region is given the "Fill Color". The current gradient fill defaults to dynamically between these two colors. Clicking either will bring up the Colors Dialog to select a new color.
In addition to these two controls, there are two smaller controls located in the corners between them.
The arrows on the upper-right side swap the outline and fill colors. 
The two little squares on the lower left reverts the outline and fill colors to their default of black and white respectively.
