MetalTheme provides the color palette and fonts used by the Java Look and Feel. 
 MetalTheme is abstract, see DefaultMetalTheme and OceanTheme for concrete implementations. 
 MetalLookAndFeel maintains the current theme that the the ComponentUI implementations for metal use. Refer to 
MetalLookAndFeel.setCurrentTheme(MetalTheme) for details on changing the current theme. 
 MetalTheme provides a number of public methods for getting colors. These methods are implemented in terms of a handful of protected abstract methods. A subclass need only override the protected abstract methods (getPrimary1, getPrimary2, getPrimary3, getSecondary1, getSecondary2, and getSecondary3); although a subclass may override the other public methods for more control over the set of colors that are used. 
 Concrete implementations of MetalTheme must return non-null values from all methods. While the behavior of returning null is not specified, returning null will result in incorrect behavior. 

It is strongly recommended that subclasses return completely opaque colors.
To do otherwise may result in rendering problems, such as visual garbage.
