Is there a way to change a switch or button background color from inside the flow? For example, if I click on a button with a green background, I want to turn it red.
Are you referring to node-red-dashboard ?
Yes there is a way. You can use the template node.
You can read some hints here
Thanks for the tip- I learned something today. I did not know that I could make buttons using the Template Node. I like that md-button class="vibrate filled touched bigfont rounded" vibrates on the phone since that's where this flow will be used.
I haven't seen how to change the button background color. Once a button is pressed, I want to permanently change the background color to indicate to the user that this button has already been pressed.
