If you are working in MATLAB, it is pretty easy to pull in the latest CheerLights color and work with it.
thingspeak_data = webread("http://api.thingspeak.com/channels/1417/field/2/last.json"); color = thingspeak_data.field2
And, just in time for Halloween, I created a CheerLights-inspired pumpkin illuminated with the latest CheerLights color… FearLights! If hit “Remix” on my code and re-run it, you will likely get a slightly different pumpkin. It has been fun to play with.
