  /* State colours. Named for the clinical state, never the hue, so the palette
     can be re-themed without touching markup or data.

     Green is ON and indigo is EXTRA on purpose: everyone reads a traffic light,
     and an earlier scheme where green meant "too much movement" invited a
     patient having a good day to log dyskinesia.

     Off and on are the two commonest states and are the classic red-green
     confusion pair, so they are separated by LIGHTNESS as well as hue — off is
     dark, on is clearly lighter. Around 8% of men cannot tell the hues apart;
     they can still read the chart by tone. Never add a state that relies on hue
     alone. */
