Trying to finish my paladin today. Still some work to do on the horse. #WIP

The noosphere is pulling no punches today. This is the more tame content.

I’m here for it.

Today I got the chance to ask our computer graphics professor a question that I asked myself quite some time ago: what the fuck is the color pink?

Like, the color right before infrared is red, the color right before ultraviolet is violet. And every other color is some wavelength between those two colors. EXCEPT FOR PINK!?

On a hue color wheel pink is between red and violet, so it's wavelength has to be somewhere around there, right??

Well, turns out pink is the color humans perceive when red and violet are mixed (duh), meaning the red and blue cones are stimulated. Since both cones respond to wavelengths on the opposite ends of the visible spectrum, there is no monochromatic wavelength that would trigger both, hence there is no wavelength that looks pink.

That's also the reason pink does not appear in a rainbow, because there white sunlight light, a mixture of (almost, hi Astro-fedi) all monochromatic wavelengths, is refracted based on wavelength, so no mixed colors occur in it.

Staff at the Guardian and Observer are on strike today (Wednesday) and tomorrow, over the proposed sale of the Observer to Tortoise media by the current owner, the Scott Trust.

I won’t be sharing articles or accessing their site/app for the duration of the strike in solidarity with those workers.

Will you join me? Please do boost, repost and share and encourage others to send a message to the Scott Trust.

I know a lot of you are like "Twitter is full of Russian spam bots" but if you saw my Dad's Twitter account, you wouldn't believe it when I told you a real person is sat there typing that, and it's my Dad.

Here we gooo!
