Forgive the color sperging, but a lot of people don't realize that there is no such thing as a "true gray". Every gray has an undertone to it, whether it's blue or green or red. Even the darker colors with just black colorant have a shade of blue to it, because the black colorant has an inherent blue hue to it. That said, even the slightest color lighter then black would be considered a gray or an "off-black" depending on what fancy pants you're talking to.
