I’ve been talking with Carista for a while about this and have sent screenshots and photos of my screen in the car. They’re working on getting the colours working but they said it’s tricky.I've found the ambient light settings to be very buggy. Can't remeber the exact wording, but there are some options like 'enable ambient settings in the info screen' unituitively this needs to be disabled! Same with a similar setting for drive mode. I'll double check when I go on my lunch break.
My issue is I've been able to enable a 9th and 10th colour option (green and purple) respectively, but when I pick one of those colours the infotainment and digital dash change to green for example, but the doors stay then same as the last standard colour that was picked. On the flip side it allows you to have different colours for the info screen and the doors which is quite cool.
Fingers crossed they get it working soon as it would be cool to have green or purple and other colours.
