Hello guys, i ' m a new owner of a skoda octavia 3 fl, with ambient lighting, now i have a big question. Has anyone changed the green colour of the buttons? If so, how to do it, is it hard, what do you need? 
I would want, if possible, to mach the ambient light with all the bottons.

Assuming you want the backlights to be white, it's easy to do the steering wheel buttons and climate panel - they just need swapping for versions with white backlights.

 

If you want to do the buttons near the gearstick and the window up/down buttons, I think the only option is to remove the old LED's and fit white LED's in their place

 

I've not seen anyone fit RGB LED's to match the ambient lighting colour I'm afraid.
