Bootstrap Dark

Bootstrap Dark is the framework's near-black, used for the default navbar in dark mode and for emphasized text on light backgrounds. It is not pure black; the slight blue cast keeps it from feeling oppressive against neutral grays and softens edges in long blocks of text. The hex is shared across many shipped Bootstrap sites, so users have learned to read it as header chrome even without conscious recognition. White or near-white works for body text on top. A saturated accent color works for primary actions; stacking two near-blacks of similar lightness loses hierarchy.
