This value is useful when you are using Canvas controls to create custom controls. When drawing controls like dividing Lines and GroupBoxes, use this color for the dark portions of the object (usually the right and bottom sides of the object).
This value can be changed by the user, so you should access this value in the Paint event handler rather than storing the value.
