I did wonder how certain octopus color matching occurred, if they couldn't perceive color... The birrin see better in low light that humans, but in less detail, particularly for distant objects

This brings up an interesting question: clearly birren see colour, and roughly share the human visible spectrum. How do they see colour? Do they have cells equivalent to the cones in human eyes? Are they trichomatic, tetrachromatic, or something else? A recent paper suggests that while octopuses only have one cell-type in their eyes, they use chromatic aberration to distinguish colour. <a href="http://news.berkeley.edu/2016/07/05/weird-pupils-let-octopuses-see-their-colorful-gardens/" rel="nofollow noopener" target="_blank">http://news.berkeley.edu/2016/07/05/weird-pupils-let-octopuses-see-their-colorful-gardens/</a> <a href="http://www.pnas.org/content/113/29/8206.full" rel="nofollow noopener" target="_blank">http://www.pnas.org/content/113/29/8206.full</a>
