URC7935: When I change the color, some keys still make the ring light up in yellow and/or green?

The color change only applies to the keys that control the streaming device. If you have set up a TV, the keys that control the TV will make the ring light up in yellow, and if you have programmed an Audio device such as a Sound Bar or Audio Video Receiver, the Volume Up, Down and Mute keys will make it light up green.
