What's the name of the online game where you're a fox that has to return color to the world?

You can also fly and you have to fight monsters to get paint. There are quite a few levels and a never ending level. It's got really nice backgrounds and music. You also collect dragonflies if I remember right. It's a free online game. It's named after the fox you play (he can fly) and it starts with a c or k. Can anyone help?
