Instances of this class manage the operating system resources that
implement SWT's RGB color model. To create a color you can either
specify the individual color components as integers in the range
0 to 255 or provide an instance of an RGB.
Application code must explicitly invoke the Color.dispose()
method to release the operating system resources managed by each instance
when those instances are no longer required.
