  1. I also saw '71' the first time. I think it just means we looked too quickly.

  3. When someone is color blind it doesn’t mean that they see no colors. It’s not like they see everything in shades of gray except in very rare instances. Being color blind means that you have trouble seeing red, green, yellow, blue or some combination of these

  6. I only made out 12 and 3. A pity I work with colors on very expensive machines. It is my well kept secret. I got some other advantages in life though. I just have to explore them now.

  7. I believe that you made cool resolution when you picked up this topic of this blog article. Do you as a rule compose your blog entries alone or you work with a partner or even a helper?

  13. Thanks for the test, it's very helpful to have multiple color plates to test from. If anyone is having trouble with their color vision, and are looking for treatment for colorblindness, I recommend trying the ColorCorrection System, which has a 100% success rate at passing the Ishihara Color Plate Test....

  15. In some of these, I can see both answers superimposed, and I'm confident that I'm not color-blind (since I use broad and fine color distinctions extensively in my work). But I can imagine scoring low by picking the wrong one during an examination, or by refusing to pick just one owing to both options being equally strong to me. What do examiners do in cases like that?

    1. Just a tad random there.
      I think these tests are a little over-difficult. Sitting in front of a tv doesn't help the situation, and with everyone watching tv or on their mobile contraptions I fear we'll all become partially color blind.

  22. I think that these tests should be used on an individual basis. I have been an offset press operator for over 32 years. I can see color density's that very by 1 or 2 points by eye on a multitude of colors but cannot answer all of these tests correctly.

  23. Good luck to all of those of you who failed the test. I feel for you, even though I'm not color blind myself.
