I've got an MQTT buffer feed of the RGB values of a coloured switch press

e.g. press red - get [255,0,0], blue get [0,0,255] etc

I'd like to have a switch that routes each colour to a different output but there doesn't seem to be a switch comparison operator to do that

Any ideas?

As a workaround - I've set the MQTT out to be a base64 encoded string and then just used string comparison
