Add some color to somebody's holiday with a coloring book

What better way to add some color to someone's holiday than with a coloring book? With Kalle Svenson's Colorize your photos, converting your existing photos into ones with a coloring book effect is a simple drag and drop away. After dragging in your photos, you can make granular adjustments to the levels (fewer or more) of detail, as well as black and gray levels. In the above photo, my man Tobias Funke, originally covered up in Blue Man Group blue, has been colorized so that I can color him into whatever hue of blue my heart desires.

One thing missing in the app that I'd like added is the ability to compile a coloring book. But this isn't that big an issue, as one can compile PDFs using Preview.app. Also, if you already own Adobe Photoshop, you may find that some of its built-in filters achieve a similar effect.

These things aside, Colorize your photos is a straightforward and easy-to-use app suitable for both kids and the kids within us. Colorize your photos is available for purchase for USD $24.95, and as a free download trial.
