What is the significance of color universal design?


For universal access, "confusing color combinations" should be avoided in documents that may be read by people with color vision deficiency (CVD). However, for people with normal color vision, it is not easy to imagine which color combinations are confusing for individuals afflicted with CVD. Variantor helps you to understand what the world looks like to color deficient people. You can easily see the confusing color combinations just by wearing Variantor.


--Color Universal Design--
There are significant variations in the perception of color. So-called "people with color-vision deficiencies" (also known as Daltonism, color-weak people, colorblind people, or people with color-vision defects, or dyschromatopsia) account for the largest proportion of those who have different color vision from ordinary people. In Europe and the US, one out of every 10-12 males and 200 females is believed to be color-vision deficient, with a total of over 10 million in the US and around 2 million in the UK. Color Universal Design is a user-oriented design system, which has been developed in consideration of people with various types of color vision. It allows information to be accurately conveyed to as many individuals as possible (from Color Universal Design Organization, Japan).
