KColorCells offers one way to present a pre-selected range of color
choices, and may have more rows and columns than displayed here.
Click on a cell to select a color.
KColorCombo provides a programmable drop down list of colors to select
from.
Finally, KColorPatch will display a specified color. In this example, using
any of the other three widgets to select a color will change the color of
