Talk:Color blindness
Color blindness was one of the Natural sciences good articles, but it has been removed from the list. There are suggestions below for improving the article to meet the good article criteria. Once these issues have been addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake. | |||||||||||||

Famous colour blind artist
Clinical and Experimental Optometry has an article showing that Clifton Pugh on biographical, inheritance and other grounds was was a protanope. I have looked hard but cannot see any place suitable for this information in the article. There is no section for "notable color blind people" though such sections exist for example for Prosopagnosia. I have put this information with reference (more details are in the online abstract) in Color blindness and occupations though this is not the ideal place. However the information is important since it shows that color blindness should not stop people for seeking to become artists if that is their talent.
wrong statistic values?
In the table "Prevalence of color blindness" there is an "overall value" of 0.49 to 1% although the difference races have far lower values? Is this a typo? — Preceding unsigned comment added by 217.231.103.179 (talk) 14:42, 23 April 2013 (UTC)
- I suspect someone became confused between percentages and straight decimals. Given how the unweighted average of the male figures is a little below the lower bound of the "overall" stat, and the unweighted average of the female figures is a little below ONE HUNDREDTH of the same - and there's information in the bodytext suggesting the "total" is correct - I propose that the individual "by race" figures need to be multiplied by 100. IE increased from 0.0016 ~ 0.0064%, up to 0.16 ~ 0.64% (or 0.0016 ~ 0.0064 when expressed as a decimal).
- With appropriate checks made at the source, of course - along with sensible sanity checks and second-sourcing if that still looks suspicious and badly proof-read.
- Alternatively it could be that there's a component of the global female population that's neither caucasian, african or asian, and makes up a high enough proportion of the total with a high enough instance of colour blindness to skew the overall result... 193.63.174.211 (talk) 08:42, 3 May 2013 (UTC)
edit request - classification: by cause: dichromacy: protanopia
This bit is rather strangely written, to whit the middle sentence:
" It is a form of dichromatism in which red appears black and therefore human can see light only from 400 nm to 650 nm. "
I wonder if this was machine translated from another language maybe? :) ... It also doesn't give any hint about the relevance of the wavelength figures, as they have hardly been discussed at all in the text up to this point.
How about:
"It is a form of dichromatism in which the subject can only perceive light wavelengths from 400 to 650nm, instead of the usual 700nm. Pure reds cannot be seen, instead appearing black; purple colours cannot be distinguished from blues; more orange-tinted reds may appear as very dim yellows, and all orange-yellow-green shades of too long a wavelength to stimulate the blue receptors appear as a similar yellow hue."
Or similar? 193.63.174.211 (talk) 08:35, 3 May 2013 (UTC)
- Done precisely as suggested. (I'm trusting you on the facts here, on the general principle that people who can write clearly usually can think clearly.) Looie496 (talk) 16:01, 3 May 2013 (UTC)
Rename article to "Color vision deficiency"
The article should really be renamed to "Color vision deficiency" and "Color blindness" redirect to it. As stated in the article it is more common to be deficient in color vision, but not lacking it! Therefore color blindness (not perceiving colors at all) is a special/maximum case of color vision deficiency. Using color blind for describing a condition with a broad range is a very unprecise top-level term, derogatory, and perpetuates ignorance.
Thanks for considering the renaming.
