Instances of the SystemColor class represent colors used in the system desktop. You can use these colors to produce applications and custom components that fit well in the desktop color scheme. On platforms that allow the desktop colors to be modified dynamically, the actual color represented by these symbolic system colors may be dynamically updated.
The SystemColor class does not have a constructor, but it defines constant SystemColor objects that represent each of the symbolic colors used by the system desktop.
If you need to compare a SystemColor object to a regular Color object, use the getRGB() method of both objects and compare the resulting values.
