 #### Examples :id=indicator-examples
 
 This example sets the modifiers to be a specific color based on the layer state.  You can use a switch case here, instead, if you would like.  This uses HSV and then converts to RGB, because this allows the brightness to be limited (important when using the WS2812 driver).
