When I put the car in green mode it shows green in the speedometer and "sometimes" the green led shows up around the center cluster. At other times, without touching any dials or doing anything different the led around the center dial shows the tach and nothing I can do changes it. I can move the dial to change to green and although it shows "green" in the speedometer the green led does not. I have a 2015 4 door hardtop that I just purchased.

 

I believe you can change it in the display settings to match the color of your mood lighting. There's a toggle up on the roof that will change the interior mood lights to different colors. The ring will then change to the set color.

 

There are settings under Center Instrument.

1. Menu button.
2. "Settings"
3. "Center Instrument"
4. "Basic display" or "Event display"
5. Select desired setting.

You can choose if it shows the tachometer, temperature changes, connection with the phone, etc...
