how do i get the default button backgrounds?

i am implementing a recording facility for my software, and am trying to implement the buttons so that when the record button is pressed, a boolean is switched and the colour of the buttons back ground is set top red.

This all works fine, but when i try and change it back when i press the stop button, it simply changes to a solid blue and not the nice pretty faded blue, metal kind of look that is offered as a default.

If any one can tell me how to set the back ground to the default that would be great.

button.setBackground(UIManager.getColor("Button.background"));

Thank you very much that was more than helpful.

Dont suppose you know how to undepress the buttons. I have a play mechanism, and at the moment while it is playing, it stays depressed, i want to change it green whilst irt is playing, but it wont undepress whilst its playing.
