FYI -- That is not a perfect black. If you check the code, it has just a hint of "something" in it. HTML# = 020202. Black is 000000. The same would be true for an off-white. As long as there is a wee bit of "something else" in the code it is off-white.
Hope this helps. By the way, I determined this by using a handy little tool called Pixie from Nattyware.
