just a real quick reply here. I ended up getting a dark "Dolphin" grey after seeing a van on the line with it. It was a custom order for a high-er profile client, and when I asked, I was told it wasn't a standard color. We weren't super impressed with the then-standard colors, especially for the 'vision' we had for the van, but this charcoal was the right direction. I was told if I wanted it that much, I could pay for the custom material from their provider, but I would have to pay for much more than they would need because "they can go through a lot of material to get a cabinet right'.
I did have to pay a little more extra ($1200 I think) but it definitely was worth it for my van plan. Now I think that color is standard.
Also, look at my layout and the layout with the "ash" above! very similar.
