Usability Quote of the Day

The web is more a social creation than a technical one. I designed it for a social effect - to help people work together - and not as a technical toy. The ultimate goal of the Web is to support and improve our weblike existence in the world. We clump into families, associations, and companies. We develop trust across the miles and distrust around the corner. -- Tim Berners-Lee, Weaving The Web   (via interaction-design.org)

How to make figures and presentations that are friendly to color blind people

This is a scholarly article about colorblindness and web page suggestions to accommodate this disability ...

"Color blindness is not a total loss of color vision. Color blind people can recognize a wide ranges of colors. But certain ranges of colors are hard to distinguish.

The frequency of colorblindness is fairly high. One in twelve Caucasian (8%), one in 20 Asian (5%), and one in 25 African (4%) males are so-called "red-green" colorblind. It is commoner than AB blood group.

There are always colorblind people among the audience and readers. There should be more than TEN colorblinds in a room with 250 people. (50% male and 50% female) There is a good chance that the paper you submit may go to colorblind reviewers. Supposing that your paper will be reviewed by three white males (which is not unlikely considering the current population in science), the probability that at least one of them is colorblind is whopping 22%!
[ 22% = 1-(1-0.92)^3 ]

When preparing your presentations (papers, slides, web pages etc.), please take this into account. Here are some comments on how to make figures and presentations colorblind friendly."   continued ...   (Via J*FLY)
