Color Oracle

Suggestion for a new App:

Color Oracle
http://colororacle.cartography.ch/

Briefly, it's a free program allows you to view the entire contents of you screen in "colorblind" mode so that you can ensure your presentations and diagrams can be read by those who do not have full color vision.

Personally, I like to use it mainly for graphs to make sure each data series can be told from the others even for colorblind people.

From the Website:
"Color Oracle is a colorblindness simulator for Window, Mac and Linux. It takes the guesswork out of designing for color blindness by showing you in real time what people with common color vision impairments will see.

Color Oracle simulates deuteranopia, protanopia and tritanopia. These are extreme forms of color blindness – most color deficient viewers are seeing more colors. Therefore, if you design your art for people with extreme color blindness, it will also be easily readable by those with minor color blindness and "normal" vision.
The number of people affected by color deficient vision is difficult to measure. Depending on the literature, one can find percentages between 1% and 12%. What is certain, however, is that color vision deficiency almost exclusively affects males. Color Oracle uses the following numbers:

Deuteranopia or deuteranomoly: 5% of all males.
Protanopia or protanomaly: 2.5% of all males.
Tritanopia: Less than 0.3% of women and men."
