Midnight Keyboard

My multi-color keyboard backlight uses RGB Light Emitting Diodes. Each RGB LED has three internal LEDs that emit red,  green,  and blue light. These can be combined at 256 different intensities to create 16, 777, 216 different colors. For example,  to emit red light the red intensity is set to the highest and the green and blue are set to the lowest intensity. To emit a cyan color the red is set to the lowest intensity and the green and blue are set to the highest intensity.  The color of the 102 keys on my keyboard can be set independently. Therefore,  there is a seemingly infinite number of different patterns  and combinations available.
