ColorViz is an augmented reality Windows Phone 7 application that helps red/green colorblind people distinguish colors in the physical world around them. It does this two ways:
1) By providing RGB values (and in the future, color names)
2) By applying some processing live video with some algorithms I have been developing for quite some time. This algorithm applies red or green filters to live video and dampens other colors.
The latest development version can be downloaded here. You must be running Windows Phone 7 Mango.
Please submit bug reports, praise, comments, and requests to @codejake on Twitter. I am particularly seeking input from other colorblind people, as colorblindness varies.
