Phenomenon

Something I been curious about is why all or most penguins are black and white, who came out with those colors or why those colors? Is it so they blend can blend with the snow. I love penguins, I think their the most beautiful animals, when they walk they look so innocent. When at I see penguins I see beautiful flightless birds, they look beautiful with their black and white fur, but they all look the same. They have white and black spots or patterns all over their bodies. What if their black or pink or red?
