I always think of it as a 'winter white'. it isn't a brash, sharp, bright white. it is just muted enough to make it look classy, not so much that it makes it look dirty or off-white. it does have a metallic sheen to it, but it doesn't stand right out as metallic.
More pics probably don't help, but here are a couple of mine. I think the one below is particularly helpful in seeing the color.
If you're avoiding a yellowy colour, don't get Old English White. Although it wasn't officially sold in the US, I think one or two came out of the custom shop and made it to the States as late '05s or early '06s.
Anyone else remember the days when white was the most sought-after colour 3 or 4 years ago?
