I am creating this page because the page pigments seemed to have two disparate subjects: pigments (art, decoration, manufacturing, etc.) and pigments (animals and plants, biological processes). I am moving material over from the other page. There are some links that need to be redirected too. Biological pigments and pigmentation is really a separate topic and needs its own page. --Metzenberg 00:16, 19 July 2006 (UTC)[reply]

Things to do ... Go through links to the pigment page and make links that relate to biology and biological processes point here instead. --Metzenberg 00:37, 19 July 2006 (UTC)[reply]

Hemocynanin, which on this page is placed under the classification "Heme/Porphyrin based", is actually not based on a porphyrin structure but instead uses prosthetic histidines to complex copper ions, which you can read about on the Hemocyanin page. Thus, the classification here needs to accomodate that. I would suggest it should be moved to "proteinaceous". — Preceding unsigned comment added by 69.80.184.22 (talk) 17:49, 26 October 2011 (UTC)[reply]

Luciferin and bioluminiscence

I think a pigment absorbs light. It doesn´t produce light. So luciferin (and in general bioluminiscence) is not a pigment... technically speaking. Actually, light is made of many wave lenghts of light. A pigment just absorbs some wave lenghts of light and reflects others, and the wave lenghts it reflects produce in our eyes the perception of color. Luciferin doesn't reflect light, instead it can produce ligth in total darkness by means of a chemical reaction.--Miguelferig (talk) 17:36, 7 January 2012 (UTC)[reply]

First image

Is it just me, or is it a little silly to have the first image on the page about pigments be of something that is specifically NOT a pigment? — Preceding unsigned comment added by 71.93.196.243 (talk) 10:34, 10 June 2013 (UTC)[reply]

Agreeing with the above. Beautiful photo of a beautiful animal, it enriched my life, I'll be sorry to see it go, but it could be added to the WikiP article ABOUT that very butterfly. Fire-opals are beautiful too but you wouldn't use one to illustrate THIS article.69.86.65.12 (talk) 09:12, 11 October 2013 (UTC)Christopher L. Simpson[reply]

Non-Marine Animals?

There is a section on plants, and a section on animals. That on animals has a sub-section on marine-animals. I scrolled below it to find the section on non-marine animals. Where is it? What am I doing that keeps me from finding it?69.86.65.12 (talk) 09:12, 11 October 2013 (UTC)Christopher L. Simpson[reply]
