Sensorial/Ambience setting

I have set a profile on my DS7 and have tried to get the ambience to default to Cashmere (Blue),ambience/sensorial setting

It changes after setup, and I have saved it but when I turn the ignition off it reverts back to the Titanium (Red) setting.

Is there a way to set the default to Cashmere?

I might be wrong but I think some of the ambient lighting reverts back by default.
Sport mode for instance is red by default, so if I change mine to say blue, it will revert back to red the next time I start the car.
I think Comfort mode might be the same, its a blueish colour by default and reverts back to that after restarting.

I havent really sat and played around with the ambient lighting that much so I might be wrong.

No go.

Will try that setting, Thanks
