How come penguins are black and white?

They're not!

Of course, while traditional tuxedos (and penguins) are black and white, there are exceptions. Just as there are those who wear lime green tuxedos with matching cummerbunds to their high school prom, so there are penguins that break the black-and-white mold. Fairy penguins have dark blue feathers in place of the black, which is why these birds are also called "Little Blues."
