The nearest I can come up with is Burgundy, but that car in the photos above looks to be much darker than the one at the 33second mark in this video from Nissan Europe:
Nissan also did a chestnut bronze colour that I liked a lot in the past.
I'd have to say that this is the favourite of all the colours I've seen so far.
I remember when I first found the Ariya, many months ago, there was a featured color with the upcoming launch of the Ariya in Japan that was Black Red. Not sure I'm remembering the color name correctly. Maybe?
Those photos were taken in the UK, hopefully they'll release the full spectrum across all regions. I hate when manufacturers don't make all colours and accessories available in all territories. It's a real pain.
We're such a small market we tend to get a poor choice at a premium price. It's improving though. Slowly.
This might be the Northern Lights color which could come out as dark purple under a cloudy sky, like in the photo. If you watch this YouTube video around the 0:45 mark, it's brown-ish. That paint color is insane - can go from bright purple to dark green to black depending on the light and angle.
