Take the Colorblindness Test
In the world of color, many factors impact the ability to
reproduce good color. The most basic (and often overlooked) factor is
the ability to see color correctly. The lack of this ability is called
colorblindness. About 8% of the male population suffers from
colorblindness, while less then 1% of females do.
There are different types of colorblindness that affect which colors
cannot be perceived as different, and how limited the differentiation
is. Surprisingly, many eye doctors do not administer colorblindness
tests as a part of the routine eye examination.
Although we all know that the colors viewed on your computer's monitor
are not accurate for print reproduction, your screen color is probably
good enough to yield reasonably accurate colorblindness test results.
We invite you now to test yourself for colorblindness on-line.
Color Blindness Tests
Begin with the simplest of tests by Alan R Miller of New
Mexico Tech.
The most famous colorblindness test was created by Dr. Shinobu Ishihara
of University of Tokyo. If you visit an ophthalmologist you will most
likely be given some variation of this test. Click here to take the Ishihara Test.
A variant of this test specifically designed for pre-school children
using shapes instead of numbers has been created and is sold by Dr.
Terrace L. Waggoner of the Staff Naval Hospital Pensacola . Click here
to take
the Waggoner Test . His site also contains a wealth of general
information about color vision deficiencies.
A unique and very interesting variant to most conventional
colorblindness tests has been developed by Aaron Clauset of Haverford
College. Unlike most tests, which require good color vision, only the
colorblind can pass his tests! Click here to take the Clauset Test.
Aaron's friend and collaborator Nick Yee even takes this test a step
further on his website by including a graphic that reveals one thing to
the colorblind and another to those with normal vision. Click here to take
the Yee test.
This test does not constitute medical advise. If, after taking these
tests you believe that you may be colorblind, Copresco suggests that
your next step be to find an optometrist or ophthalmologist who is
comfortable diagnosing and evaluating colorblindness.
In Conclusion
Remember, colorblindness comes in varying degrees. Just because someone
doesn't run stoplights doesn't mean that won't have difficulty properly
evaluating accurate color reproduction on the printed page!
