Lumar toggle button

The Lumar toggle button is a button added by RedLogic. It has 16 different colors that it can glow in. If the player presses it, it emits a continuous redstone signal until the player presses it again. Its modes can be switched between by shift right-clicking on it with a Screwdriver:
 * Default: The light turns off when the button is pressed.
 * Inverted: The light turns on when the button is pressed.
 * Always on: The light is always on.
