   9 Using binary brightness makes more sense for this controller, because
  10 internally in the MCU it works that way: the LED has a color, and a
  11 state whether it is ON or OFF.
  12
  13 The resulting brightness computation with led_mc_calc_color_components()
  14 will now always result in either (0, 0, 0) or the multi_intensity value.
