I'm trying to implement a webradio with a Raspberry Pi, node-red and MPC, that can be controlled with a LIRC IR window control.  
The station selection should indicate the current station in color.  
I have found an example with led display.  
[[https://flows.nodered.org/flow/a7f16a3f276ac5cb51e5c760572afd8e](https://flows.nodered.org/flow/a7f16a3f276ac5cb51e5c760572afd8e)]

My modification changes the color of the button, but the station changes shortly and then only station 1 is played.

I was looking for an example here where buttos change color without changing the output. None of them I understood for my application.  
It would be nice if someone could help me.

I don't know if you have [seen this topic](https://discourse.nodered.org/t/examples-of-colour-change-button-and-switch/3650), but it would seem to provide a good starting point for your problem.

If you have older dashboard, this may be labelled differently (like pass through msg)
