Talk:Eye color

Contradictory assertions about blue pigmentation

From the section Classification of color:

There are three pigment colors that determine, depending on their proportion, the outward appearance of the iris: brown, yellow, and blue.

From the section Blue:

There is no blue pigmentation either in the iris or in the ocular fluid. Dissection reveals that the iris pigment epithelium is brownish black due to the presence of melanin.

Am I missing something, or are these contradictory? Duoduoduo (talk) 18:42, 12 December 2012 (UTC)

The problem is the use of the word "pigment" in the paper by Seddon et al. It's clear that in their work they merely classified eye colors based on the appearance of photographs. When they say write of brown, yellow, or blue "pigment", they just mean coloration, as seen in the pictures. The lead and the discussion of blue, green, and grey eyes in this article make it clear that human irises have only one pigment, melanin, which is always brownish-black. The external appearance of the eye is a structural color, given by the interplay between pigmentation and the scattering of reflected light in the stroma or the iris. - Eb.hoop (talk) 19:10, 14 December 2012 (UTC)

Perhaps we need to mention structural color an extra time to avoid confusion. Chiswick Chap (talk) 19:13, 14 December 2012 (UTC)

Green Eyes

Both of the photos for "green eyes" in this article feature pictures of an iris that is primarily brown with *some* green around the peripheries.

I have tried on two occasions to provide pictures of an actual green eye -- ie. not a "brown" eye with "some" green - but an actual 100% green iris, and both times these edits were reverted.

What gives with this? — Preceding unsigned comment added by 75.253.67.46 (talk) 08:01, 21 December 2012 (UTC)

Both of the current pictures look hazel to me, as per the description in the section hazel.

I can't find your reverted edits in the edit history -- what dates and times did you make them? I'd like to take a look at them. Duoduoduo (talk) 15:26, 21 December 2012 (UTC)

Hazel eye picture

Currently there is no picture in the Hazel section. But the right-side picture of the Green section, strikes me as obviously hazel: it fits perfectly this passage from the section Hazel:

This can sometimes produce a multicolored iris, i.e., an eye that is light brown/amber near the pupil and charcoal or dark green on the outer part of the iris (or vice versa) when observed in sunlight.

Yet the picture itself is labeled "Green eye". I suspect this label on the picture was incorrect OR on the part of the person who uploaded it. Can the label be corrected and the picture moved to the hazel section? Duoduoduo (talk) 20:11, 24 December 2012 (UTC)

Grey eye isn't Grey

Just wondered why the 'Grey Eye' in this article is actually Aqua blue/green mix and not grey? — Preceding unsigned comment added by Jackson121412 (talk • contribs) 17:07, 7 January 2013 (UTC)

Black eyes

I reverted these edits by Wikkedout because, like I stated in that edit summary, the editor needs WP:Reliable sources stating that true black eyes exist. As it stands, the editor added nothing but WP:Original research; for three parts, also seen in that link, he or she also changed text that is supported by three different reliable sources. And the formatting style, capitalizing both "brown" and "black," violated Wikipedia:Manual of Style#Section headings. Flyer22 (talk) 00:04, 18 January 2013 (UTC)
