"I used to liked yellow but I got fed up with it."What flower colours do birds and bees prefer? (ABC, 16 November 2016) Bees see blue, green, and ultraviolet; some birds are "violet-sensitive", seeing red, blue, green, and violet, and some are "ultraviolet-sensitive" and see that part of the spectrum as well. Most Australian pollinating birds are violet-sensitive; plants may have red hues which attract birds, their preferred pollinators, but not bees. The flies that do the pollinating on Macquarie Island prefer a "yellow-green-cream colour".

Female lemurs with color vision provide advantages for their group (phys.org, 5 December 2016) About a quarter of the female Verreaux's sifakas were trichromats, able to distinguish green and red; females tend to lead groups in foraging.
Disordered nanonetwork produces robust and vibrant colors for vehicles, biomimetic tissues and camouflage (phys.org, 28 November 2016). Borrowing the structure of the cotinga's brilliant feathers to create "metamaterials".
these are colorblind glasses.
This Artist Is the Only Person Banned From Using the World’s Pinkest Pink (Smithsonian magazine, 16 December 2016) The feud behind this is a
riot.
"'I’m color-blind, but I can pick out that blue anywhere,' [Eddie] Redmayne said and walked toward the painting in a sort of trance. 'I wrote 30,000 words on this color, and I never grew tired of it. The pigment is staggering. It’s amazing that a color can be so emotional. One can only hope to achieve that intensity in acting.'" (
W, 1 April 2013). Presumably Redmayne is red-green colourblind. It'd be interesting to know if and how this affects his experience of International Klein Blue. But my understanding of the science of colour vision is still crap. See also:

Listen with your eyes: one in five of us may 'hear' flashes of light (Guardian Australia, 17 January 2017). "One in five people is affected by a synaesthesia-like phenomenon in which visual movements or flashes of light are 'heard' as faint sounds, according to scientists."
The Colorful Stories of 5 Obsolete Art Pigments (Hyperallergic, 2 July 2013) |
More Vibrant Tales of Obsolete Pigments (Hyperallergic, 8 July 2013). Maya blue, Tyrian purple, white lead, lapis lazuli, dragon's blood, mummy brown, Indian yellow, Scheele's green, orpiment, hartshorn, ivory black, Paris green, iris green, sepia ink, smalt, uranium yellow, gamboge, and verdigris. Whew!
As I was making this posting, I realised I was remembering the dates of the articles partly by the colour of the years - that is, I have Grapheme-colour synaesthesia, and associate a colour with the last digit of the year; deep brown for "6", for example. I often find it difficult to keep the date in mind as I move between the original article and my posting - I wonder if this is a way my brain can divide up the work a bit.
