Are you color blind? Do you want know if you are? Check this sites. http://colorvisiontesting.com/online%20test.htm and http://www.toledo-bend.com/colorblind/Ishihara.asp.
This morning, my colleague identified a green button as gray. I asked another colleague to get another answer. And our answers are the same, the button is green. So I inquire my first colleague if she is color blind and ask her if she already undergone a color blind test. She thought I was referring to an internet site so I asked Mr. Google if there is an online Color Blind Test. And there is! Although it is just s sample test, you can already identify if you are color blind or not.
By observation, I know that my husband has a problem identifying colors. Just to confirm that he is really color blind and not just having a problem identifying the color names, 😀 I let him took the exam. And indeed, he is a color blind.
