In a conversation a few weeks ago, it came up that my roommate is colorblind. After razzing him for a bit*, he showed me some of the “color-blind tests” that he originally failed (including some of those pictured here). So, for the past couple of weeks, there has been an ongoing discussion,
typically including a string of bad jokes, of what it is like to be colorblind, or “suffering from a color vision deficiency,” if one wanted to be more accurate. Personally, I’ve always responded to color**, and it seems like having a “color vision deficiency” would be a serious setback for the aspiring 3-year-old artist/designer. I asked my roommate, though, and he said that it had never presented much of a problem for him – because markers and crayons and pencils all have their color written on them – but when it did, he ‘would focus on expressing the emotion of the work without worrying about the colors.’***

A few interesting facts about colorblindness: “99% of all colorblind people are not really color blind but color deficient” and “99% of all colorblind people are suffering from red-green color blindness.” However, this is not necessarily the same 99 percent. Also, about 8% of all men and 0.5% of all women are suffering from color-blindness (1). The most accurate colorblind test is the anomaloscope (2), but the most common type is the Ishihara Test, which is the type pictured here.

According to Wikipedia (3), the Ishihara Test was designed by “Dr. Shinobu Ishihara, a professor at the University of Tokyo, who first published his tests in 1917.” Basically, it is a series of colored plates covered by circular dot patterns that have the form of a numeral written in the center; the number is easily visible to a person with normal color vision (and good reading-glasses). Whether or not it was his intention, Dr. Ishihara not only designed a test for colorblindness, but also a near textbook example of many of the basic design and Gestalt principles: unity, grouping by color, negative space between the dots, proximity and varied repetition of the dots, emphasis on the different color(s), balance of the plate, dot patterns, rhythm, et cetera. Once again, design and science are working hand in hand…
* All in good fun, don’t worry. His feelings weren’t hurt.
** One example: there were a couple of years in junior high I would refer to colors as they appeared in my Prismacolor marker set: “That squash is ‘Yellow Orche,’” and “Your water bottle is ‘Peacock Blue.’”
*** And I totally paraphrased his quote. Dude, please don’t be offended…
