Kwanzaa keeps people of African origin from feeling left out around Christmas time if they refuse to be Uncle Toms and celebrate Whitey's holiday. During Kwanzaa, black people dress up in clothes that don't match and dance around senselessly. This is very unusual. Kwanzaa has its own flag (pictured). To celebrate all the diversity of the holiday, it contains all the colors of the rainbow, excepting orange, yellow, blue, pink, purple, and gold. And it adds black for good measure, of course. The remaining colors are surely used by some flag somewhere and thus haven't been shortchanged.
