Leaf By Bendigo Design

Leaf is a simple application which lets you colourise images by having them first in Greyscale or Sepia or Night Time and after selection you can "Paint" them back into their original colour.
If you are familiar with flagship product, Pixo, you will feel right at home, however the difference is Leaf does the opposite of Pixo where you start off with your image already in Greyscale or Sepia and it enables you to colourise it.
