/**
 * Manages SWT color objects for the given color keys and

 * equal keys and equal <code>RGB</code> values.
 * <p>
 * In order to provide backward compatibility for clients of <code>IColorManager</code>, extension
 * interfaces are used to provide a means of evolution. The following extension interfaces exist:
 * <ul>
 * <li>{@link org.eclipse.wst.jsdt.ui.text.IColorManagerExtension} since version 2.0 introducing
 * 		the ability to bind and un-bind colors.</li>
 * </ul>
 * </p>
 * <p>
 * This interface may be implemented by clients.
 * </p>
 *
 * Provisional API: This class/interface is part of an interim API that is still under development and expected to
 * change significantly before reaching stability. It is being made available at this early stage to solicit feedback
 * from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken
 * (repeatedly) as the API evolves.
