In terms of physiology, the color is stimulated in the brain when the eye reports input from short wave blue cone cells along with a sub-sensitivity of the long wave cones which respond secondarily to that same deep blue color, but with little or no input from the middle wave cones. The brain interprets that combination as some hue of magenta or purple, depending on the relative strengths of the cone responses.
In other words, our brains are like "🤷♂️, here's a thing"
The one positive to wearing contacts all the time is that my eyes are mostly protected from UV. I always think how cool that is even if I still avoid looking directly at UV lights out of caution.
What I call Parrish light - the distinctive tone that's prominent in Maxfield Parrish's paintings.
It's a relatively subdued but clear reddish orange that I see most commonly with relatively uniform but thin thunderclouds at dusk. It makes blues and greens much more vivid, in spite of the fact that the overall amount of light is relatively low. And it's glorious.
This painting of his -- Daybreak -- has a pale red-orange and has blues and greens that sort of jump out more because of that, I suppose. Is this what you're referring to?
Daybreak, inspired by the landscape of Vermont and New Hampshire to create lush and romantic tones,[1] is regarded as the most popular art print of the 20th century, based on number of prints made: one for every four American homes.
The technique of glazing, using a varnish over several layers of paint at once helps to achieve the soft glow and whimsical style Parrish is so well known for.
Parrish referred to Daybreak as his "great painting", the epitome of his work.
Don't get too hung up on the name - it's just a personal bit of shorthand. What I'm talking about is the actual phenomenon. Parrish's paintings are just the closest popular representation I've seen of it.
It seems to happen most often in late summer, when (in my area at least) afternoon thundershowers are relatively common. There are times when the clouds will roll in, but they're not dense enough to bring rain, and just at dusk, the light through those clouds is diffused but oddly clear, so in spite of the fact that the light level is low overall, colors, and especially blues and greens, really pop.
In HSL terms, it's essentially 100% saturation but only maybe 30% light, and since the light shifts toward red/orange, the blues and greens are the colors that stand out the most.
As I wrote this, I didn't read that it was about light...
#fca4a4 sweet pink, kinda like salmon but more red on the Hue slider. I use it as my brand color! Even though I don't really use it much.
But is there a precise wavelength that it is supposed to have? Obviously different monitors will display them differently.
#F00 is a shorthand for #ff0000. I understand what you mean but it references a composition of the brightness of three LEDs on a screen not a colour of light which is when using a screen always just red green and blue in varying quantities.
