Many men have physiological issues with color perception. It would have been more interesting to make 2 polls based on sex.
Yes. It may be, too, that there is a racial vector. 'Colour blindness' seems to have an element of genetic heritability. Many animals appear to have no or only a weak sense of colour discrimination.
Also, there is a fascinating speculation that the Ancient Greeks may have had some form of mass colour blindness. This is based on the 'way-off' colour decriptions used by many of the great Greek writers and accepted as normal by their audiences. There is the line in Homer's poetry that describes the sea as 'wine-dark'. If one thinks about it, the colour *saturation* of deep, clear sea water can appear similar to the colour saturation of a full-bodied Mediterranean red wine - though of course the colour hue is entirely different. No one doubts the accuracy with which Homer set his perceptions into writing. How, other than that his audiences generally shared with him (and other such Greek writers) a distorted colour perception, can one account for for such a 'way-off' description? For any interested, there's an interesting paper here, http://serendip.brynmawr.edu/exchange/node/61 that provides several more examples.

Or, there is also the possibility that Homer was able to recognize color more acutely than we are. Think about it....
I understand that the Japanese distinctly recognize two colors between blue and violet, which they do NOT describe as bluish violet and violetish blue.

It will also be interesting to see how many of the low scorers (below 4) grade diamonds for a living. Diamond graders have to make these minuscule comparisons daily.

Fair enough.... Differently gifted?
Whatever, there have been several isolated and therefore inbred communities identified in the last hundred years in which colour blindness had become the rule rather than the exception. It is not that remarkable if the Ancient Greeks were to have been another such community - if a much older one than any other we are aware of.

This engineer got a 4 Maybe I should think about a career change
