Almost everybody wonders how a person with color blindness sees the world? Fortunately, the web page color-blidness.com can help you to understand it better. In spite of its name, the term color blindness does not mean that these people see the world in black and white.
In fact, it indicates a decreased ability to see the differences in color. Actually, over 99% of the colorblind people are able to see the real color. For this reason, the term color vision deficiency, or CVD, is thought to be more convenient.
Based on the web page color-blidness.com nearly 0.5 % of women (1 out of 200) and 8 % of men (1 out of 12) experience color vision deficiency. There are a few types of color vision deficiency, including Deuteranomalia (that makes everything to look like faded), Protanopia (that makes everything look like a bit green), and Tritanopia (that makes everything look like greenish-pink).
In addition, nearly 0.00003 % of the population experiences Monochromacy (total color blindness).
Bored Panda tested numerous different images in order to find out how different colors seem though various CVD lens. Here is what they have discovered.
