A Color Blindness Test For Printers

This is a color blindness test. Though these pictures can tell you if you suffer from color blindness, it should not replace an actual diagnosis by purchasing the real Ishihara Color Blindness Test which consists of several plates that diagnose various forms of color blindness.

Color blindness doesn’t necessarily mean only seeing black and white. I don’t profess to know all different types, but there are some that are more subtle to discover than others. Here are some different types:

* Monochromacy – total color blindness
* Dichromacy – one of the three basic color mechanisms is malfunctioning
* Anomalous Trichromacy – when colors are seen, but matched differently by the brain

Of these three color deficiencies, 10 percent of the male population and 1 percent of the female population either inherit or acquire in their lifetime.

I’ll now go back to the example in the beginning. It was just a matter of time before someone like this came along. I have worked with a few women before in the press room, but by and large most were men. If ten percent of all those who have come through have a color deficiency, then sooner or later it was bound to happen. The lesson: I had better be more preemptive.

So needless to say, all who enter my press room, must take the Ishihara Color Blindness Test. It is simple to give and saves a lot of investment from the employer side as well as employee. There are other tests that can be purchased for around $800, but I highly recommend purchasing the Ishihara plates for this purpose.

However, here is a simple test online that will help you. It is not meant as a diagnostic test, but can serve as a quick reference. Proper diagnosis should be done by a professional. Here goes.
