In Japan, Eizo plans to market a 24inch LCD "with a Colorblind system which allows people who are suffering from this problem to be able to 'see' most of the graphic display," says Akihabara News. There is already an 18in version.
The story links to the Color Universal Design website which says this is "a user-oriented design system, which has been developed in consideration of people with various types of color vision, to allow information to be accurately conveyed to as many individuals as possible."
It points out that "both Section 508 of the Rehabilitation Act in the US, enacted in 1998, and Phase III of the Disability Discrimination Act in the UK, started from 2004, explicitly call for the consideration to people with disabilities including the colorblind among others." However, as with other examples of usability-oriented design, it benefits everyone.
