The color wheel is used to select colors for drawing or filling. Select a color by clicking on the region in which it appears. In response, the wheel spins and the pointer slides up or down as needed until the pointer rests on the selected color. To select black, click on the black center of the wheel. To select white, click on the white outer rim. Once a color has been selected it will be used for all subsequent drawing and fill operations until another color is selected.
