Colour Blindness - Information and Simulations for deuteranope, protanope and tritanope, the 3 main types.

About 8% of men and 0.4% of women have some form of color blindness.

This figure simulates the web-safe colors as they appear in a deuteranopic condition.  In most other categories of color blindness, protanopia, protoanomaly and deuteranomaly, the view is very similar but there are subtle differences.  In one very rare form, called tritanopia, affecting thirty people in a million, colors appear very differently - simulation below.

Here is the main web-safe color reference.

In most forms of color blindness, these colors appear similar to those above.

Simulations of how the SOE appears to someone with deuteranope, protanope and tritanope

Deuteranope - red/green color deficit



Protanope - another form of red/green color deficit



Tritanope simulation - a blue/yellow deficit - very rare
