Use with 1 or 4 ColourTail LEDs. Interactively mixes the colour of the first LED. Hold button A to increase intensity of currently selected component (red/green/blue). The height of the three lit pixels on the 5x5 display indicate the levels of red, green and blue respectively. The flashing one indicates which component is currently selected - press B to change.
