Zwift Play light colour coordination

I really love the Zwift play controllers - they have turned my training bike into a smart bike overnight with the amazing virtual shifting feature.

I noticed the LED lights on both controllers appear to be able to generate any colour and it got me thinking.

It would be great if these LEDs could be assigned to a particular function - such as power zone or HR zone. It would be a very simple and powerful visual reminder for anyone training in zones.

I’m sure there may be many other similar uses, but power and HR options would certainly be the most useful.
