If Seat are anything like VW, don’t be surprised if they can’t tell you the paint code.
I’ve got a set of anthracite coloured alloy wheels on my VW. The wheels are VW alloys from the official VW accessories
brochure.
I’ve picked up some very small stone chips on my wheels so wanted some touch-up paint to repair them. VW aren’t able to tell me what the paint code is for my wheels, even though the wheels are a genuine VW product.
Looks like I’ll be going to the likes of Halfords to try and get a near match.
