I don't have any, and the color of your belly button lint is usually determined by your clothing. Are you, by any chance, really hairy in the nether region, with hair making a path leading up to your belly button? The hair kind of "brushes" strands of the fabric up into your belly, where it collects just because it's the spot without hair, and because it's a pocket.
