rb this with ur opinion on this shade of pink:

This is magenta, and not pink. Unlike pink, magenta doesn鈥檛 actually exist. Our brain just invents magenta to serve as what it considers a logical bridge between red and violet, which each exist at opposite ends of a linear spectrum.

TL;DR this color is fake (and also I hate it)

Wait til you learn about Stygean Blue

Your brain is a badly-designed hot mess of bootstrapped chemistry that will tell you that all kinds of shit is happening that has no correlation to physical reality, including聽time travel. It just makes things up. Your brain is guessing about what鈥檚 happening when your eyes saccade, what鈥檚 happening in your blind spot, and what the majority of the visible light spectrum looks like, and you don鈥檛 know it鈥檚 happening because it doesn鈥檛 aid your survival to become aware that a lot of what you see is fake.

The human eye only has three types of color sensitive cones, which detect red, blue, and green light. Your brain is making up every other color you perceive.

Let鈥檚 have a little fun with that thought. This is the visible spectrum of light.

You will of course note that yellow is on the chart. Yellow has a discreet wavelength, and is therefore a distinct physical color. But we can鈥檛 see it.

鈥淪orry, what the fuck?鈥

What we call yellow is just what our brain shrugs and spits out when our red and green cones are equally stimulated. We have light聽receptors that can pick up on the physical spectrum of light we call yellow: that鈥檚 why yellow things don鈥檛 just look like moving black blocks to us. But your brain has no fucking idea what the color yellow looks like.聽

Some animals have eyes that can聽perceive the color yellow! Goldfish have a yellow cone in their eyes. If they could talk, they could tell us what yellow looks like. But we wouldn鈥檛 be able to understand it.

What your brain actually sees of the color spectrum:

We can measure the wavelength of light, so we know that when we see聽鈥榶ellow,鈥 we are seeing light in that 550-ish nanometers range. But we don鈥檛 have a cone in our eyes that can pick that up. Your brain just has a very consistent聽guess about what color that wavelength of light could be. We decided to name that guess聽鈥榶ellow.鈥 We can鈥檛 imagine what yellow really looks like any more than a dog can imagine the color red.

Here鈥檚 the funny thing: your brain is never perceiving just one聽photon of light at a time. Something like聽2*10鈦 photons per second聽are hitting your retina under normal conditions.聽Your brain doesn鈥檛 individually process all of them. So it averages them out. It grabs a bunch of photons all coming from the same direction, with the same pattern, and goes,聽鈥測eah, that cup is blue, fuck it, next.鈥

That鈥檚 how colors blend in our eyes. So sure, if a photon of light with a wavelength of 550 nanometers bounces into our eyes, we see what we call聽鈥測ellow.鈥 But if we see two photons at the same time, coming from the same object, one of which is 500 nms and the other of which is 600 nms, your brain will average them out and you will still see yellow even though none of the light you just saw was 550 nms.

So how does magenta factor into this?

Well, as we鈥檝e just established, when your brain sees light from two different slices of the visible light spectrum, it will try to just average them together. Green plus red is yellow, fuck it. If it鈥檚 more red than green, we鈥檒l call that聽鈥榦range.鈥 Literally who gives a shit, we鈥檙e trying to forage over here. There are bears out here and it鈥檚 so scary.

What happens if you take the average of blue and red light, which we perceive to be magenta? What鈥檚 the centerpoint of that line?

Fucking green.

Hey, that鈥檚 not gonna work?聽We live on a planet where EVERYTHING IS GREEN. If something is NOT green, that means it鈥檚 either food, or a potential source of danger, and either way your brain wants you to know about it.

So your brain goes, WHOOPS. Okay - this is fine. We already made up yellow, orange, cyan, and violet. We鈥檒l just make up another color. Something that looks really, really different from green.聽

And so it made up magenta.

So, physics-wise, is magenta聽鈥渞eal?鈥

No; there鈥檚 no single wavelength of light that corresponds to magenta. But you鈥檙e rarely seeing only a single wavelength of light anyway. And even when you are, every color other than RGB is a dart thrown on the wall by your meat computer. This is the CIE Chromaticity Diagram:

image

Explaining this thing is a little more than I want to take on on a Saturday morning, but I鈥檝e included a link above that goes into it a little more. The point is that only the colors that actually touch the聽鈥榦utline鈥 of the shape actually correspond to a specific wavelength of light. All of the other colors are blends of multiple wavelengths. So magenta isn鈥檛 special.

Given that color is just a fun trick your brain is playing on you to help you find food and avoid danger, is magenta real?

Yeah, absolutely. Or at least, it鈥檚 just as real as most of what we see. It鈥檚 what we see when we mix up blue and red. It would be disastrous from a survival standpoint to perceive that color as green, so we don鈥檛. Because it鈥檚 not green. Light that鈥檚 green has a wavelength of around 510 nm. Stuff that鈥檚 magenta bounces back light that is both ~400 and ~700. Your brain knows the difference. So it fills in the gap for you, with the best guess it has, same as it does with your blind spot.

The perception of color exists within your brain, and your brain says you see magenta. So you see magenta.

Go study for your finals. Write that paper and finish that presentation. Study those flash cards. Stop procrastinating, have more trust in you and get off your phone.聽
