Thanks to Patrick Carroll for the work put into this tutorial.

1. Right-Click o­n the X/Y Pane and choose the Light Entity.

2. Move it around to where you want it, then press N to bring up the Entity Properties.

3. Then press K to open the Colors menu (witout closing the Entity Property Window). Choose the color you want your light to be.

4. Close all property windows (by pressing K and N again).

5. To make sure the light has taken the color you just gave it, look for the light in the 3D Pane window. The light will have the color you have selected. If the light is still white, that means the color was not affected to the light entity.
