🤔 however, in my [button change example](https://discourse.nodered.org/t/switch-button-ui-node-how-to-change-color-background-color-size/33799) it is possible:  
you have to inject:

```auto
node.send({ui_control:{onicon:"fa-3x fa-lightbulb-o",oncolor:"#e6d00b"},label:"on",payload:true});

```

and this one to change icon, color ... :

```auto
node.send({ui_control:{officon:"fa-2x fa-lightbulb-o",offcolor:"grey"},label:"off",payload:false});

```

to a Switch node , and put variables in :

@Trying_to_learn did you try this example ?  
What makes this work ? @dceejay says it's not possible? magic? lol
