Will you participate in my color blind test?

I've read statistics that 10% of men are colorblind. However, I know VERY FEW men that are color blind. Yes, I do ask.

I also know most men haven't taken a color blindness test.

So my questions are:

1. Do you know for a fact that you are or are not color blind?
2. What shapes or characters do you see in the following images?

DON'T CHEAT OR READ BELOW. These pictures have very definite answers, so cheating should not even be necessary.

For this test, I see the following, reading from left to right, and top to bottom:

58; 18; E; 17;26;45

I know for a fact I am not color blind in an interesting way. It is because my mother IS red-green color blind. Because I am a female child of hers, and my dad was not color blind, it was genetically impossible for me to be color blind. The interesting thing is, if my mom had any boys, they would have been color-blind automatically. But, she had only girls.

Now here's where it gets even more fun.

Neither my sister nor I is colorblind, but we both carry the gene for color-blindness. Assuming we have children with men who are not color blind, our girl children will not be color blind either, but half of the girls (statistically) will have the color-blindness gene just like we do.

Half the boys will not be color blind at all, and and will not carry the gene for it, but the other half of the boys will be color blind.

The REALLY interesting thing, to me anyways, is that my mom is colorblind but her brother is not. This means that my maternal grandma and grandpa must have each had only one copy of the color blind gene for my mom to be color blind. Also, it was statistically more likely that my uncle would be the one to be color blind, and my mom would not be. But that's not what happened.

Anyway. I think it's cool.

Asker's Rating:
• In case people are wondering, the actual answers are from left to right and top to bottom:

58, 18, E, 17, 26, 45.

Her's what I see:
S8, 18, L, nothing at all, 26 barely, nothing at all.

Awesome analysis!!

In my family I'm the only one that's known to be color blind. My brothers have taken my informal tests, and they're not color blind. Neither is my mother. We don't know about anyone else, because it's the kind of thing that never really comes up.

I should start sending out an email :)

1. I don't know for a fact.

2. When I did this, one of them was difficult for me. I imagine there are degrees of colorblindness. In particular, I had problems with the lower left one in the first group of four. The rest were all easy for me to see.

There actually are degrees of color blindness. There are also hundreds of types. It depends on the cause and degree of the cause.

1. I don't know for sure if I'm colorblind. I have taken similar tests for fun and I have recognized all numbers and letters. Based on that, I'm fairly certain that I'm not colorblind.

2. 58 18 E 17 26 45
E was hard. Looks almost like a P or R.
17 was hard because of that serif on the bottom that makes the 7 look almost like a 2.

The only one of the images I can read is the upper right corner of the four in a square. It's 18.

I have three brothers and we all have this. My mother must have been a carrier I guess. We found out after I attempted to join the Navy for Nuclear Engineering and failed out for colorblindness. My little brother wanted to be a pilot, and he can't do that now either.

I don't notice it day to day, and I never even had a clue until the Navy put these same test in front of me.

For those who wonder what color blind people see, you can actually check it out at the following website. To see the exact condition I suspect I have (based on testing a bunch of images), check out the following site:

I am pretty sure (not 100%) that I am not color blind, as I've taken a few of these tests before at the Doctor's office, but it never hurts to try again just in case.

Here is what I see: 58 - 18 - E - 17 - 26 - 45

I am not color blind. I take these tests every year during my yearly eye exam. (I don't think you can develop color blindness, can you?)

I see the 58, 18, E, 17, 26, 45.

I had a friend who was color blind. He went into the armed services and I lost track of him. It was kinda funny. He was a great guy and we both had a similar sense of humor. We liked to play trivia pursuit and he invariably got the color questions. (e.g., what are the colors of the rainbow) Also, back then, I smoked (but no longer) cigarette brand called Vantage I think. It had a logo of concentric circles. There was purple, dark blue and maybe a medium blue. Anyways, once I asked him if he could see the circles and he said he saw both of them. (There were three.)

A great question for me. I forgot all about this and it was very nice reminiscing.

Ha! That's awesome. I also have trouble telling the difference between blue and purple.

Did you know that color blind people were used by some platoons because, paradoxically, they were able to see enemy uniforms better than non-color blind people? Apparently the green uniforms looked orange relative to the backdrop.

I'm not colorblind - I can see all the numbers and the letter in those images. How do I know beyond that? Years of annual eye exams.

Why is it that you believe so few men are tested for this? I can recall this coming up, even before I knew I needed glasses, in my American schooling.

As an aside, I do know a couple of colorblind guys. The guy worst off is an engineer who had a hell of a time with resistor color codes.
