      The multicolor class groups monochrome LEDs and allows controlling two aspects of the final combined color: hue and lightness. The former is controlled via the intensity file and the latter is controlled via brightness file.
      Nice. A framework to use system lights as a utility instead of just bling will make me more interested in system lights.

        Actually a really good use for this tech. Around here idiot kids black out their bikes making them very difficult to see on the road.

            No.
            RGB leds will take use of it.
            Like Notification LEDs on phones.

              Network routers with Led indicators will benefit from it, too.

                A while back I wrote some iptables rules that created some led triggers when traffic was coming or going on some ports I was interested in. One could hook those triggers to whatever available leds, I chose the scroll and caps lock. They have other built-ins like a heartbeat and load triggers. Pretty cool considering there was no programming. (Outside of the iptables rules and echo'ing some stuff to /sys)
