You won’t be able to do this with a momentary switch alone since it only has a couple states that can be used to indicate a color on the dashboard. What you’ll need to do is combine your momentary switch and contact sensor into an actual garage door virtual device, and then that will allow the different states of the garage door to indicate different colors. I use this one:
Another option would be to write your own rule to update the status of a virtual garage door device based on your contact sensor status and then display that on the dashboard.
