Color Lab allows you to recolor your photos and apply various color effects to them.

It provides you the most easy-to-use enhancements for creating art photos.
You can choose to recolor your photos with vivid colors: red, yellow, blue, green or the boring black and white.
Or splash lovely colors on the boring images and make them joyful.
Surely, it lets you gray out everyone in an image, except for yourself.
You are also allowed to draw a red heart surround the girl you are in love with. Then share it into your social stream which definitely will be a romantic way to express your love and win you a sweet girl.

So much fun to play with your ordinary photos.
It lets you become the most creative painter to paint the hair yellow, the sky red, the trees blue or anything weird but wonderful.
And what you need to do is to use your fingers. One for painting while two for zooming.
