When I was on Club Penguin, I saw two things that both have to do with new colors! The first one is the color gray. Lots of penguins have been wanting this color. I think that it will come because of the holiday cookies pin. The pin has a gray car on it. Take a look.
If you were at the holiday party 2012, you will know that when you turn into a race car that car will be your color. The next color is like a super light blue. This color was first seen in the Treasure Book. Take a look at the color.
I think this might be a bug, but it might not be.
