To the previous Anonymous post, of course there are numerous types and degrees of color “blindness” but the truth is that the majority of them would have no problem designing a web site with colors, identifying a theif’s dress color and most of all would have no problems as an engineer!

As an engineer in the US, I have never come across an engineering job that tested anyone for color vision. It is ridiculous to assume that all color deficient or color blind candidates could not peform engineering jobs. There may be a few specific cases where color vision would be necessary or a very extreme case of the deficiency where it would be a hindrance to job performance, but the vast majority would have no issues whatsoever.

In India, truly speaking, colour blindness candidates are rejected if the employer feel that the colour blindness may hinder or pose challenges for the employee to perform his duty successfully. For example, in IT division, web design is most important thing. A colour blind person may not able to design a webpage with different colours. A colour blind police officer may not be able to identify the thief’s dress colour. Over all, colour perception is most important for all engineering graduates.

I have been diagnosed with mild deuteranomaly and have been disqualified from USAF pilot training. I am currently working to get an exception to policy that would allow me to still go to pilot training, and I know how difficult this will be. But I need help with research for my exception to policy package. Today I came up with a simple but interesting idea and tried researching but was unable to find the information I need.

The idea is that since I have mild deuteranomaly, my M (green) cones are shifted a few nanometers towards the L (red) cones. I also know that many other factors can affect the color perception of people with normal color vision, such as the position of the sun in the sky, weather, hazy, cloudy, etc… So what I’m looking for is a measure of how much the position of the sun would affect the color of an object. I’d bet the bank on the sun shifting light wavelength more than my condition.

I’ve looked into color temperature a bit and found at dusk or dawn sunlight has a color temp of approx. 3200 K and at noon its around 6500 K. My problem is I’ve been unable to relate this change of 3200 K to 6500 K to a change in wavelength (nanometers).

Any information on how much the sun would affect color perception, or how many nanometers a person with mild deuteranomaly would be shifted would be greatly appreciated.

There are definitely cases of color vision that I believe should not be disqualifying for ANY job. The fact that I have lived 24 years without knowing I have deuteranomaly is enough for me to say that it will never have any practical significance for me.
