The World's Only Consulting Detective

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’s 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’t see it.

“Sorry, what the fuck?”

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 receptors that can pick up on the physical spectrum of light we call yellow: that’s why yellow things don’t just look like moving black blocks to us. But your brain has no fucking idea what the color yellow looks like. 

Some animals have eyes that can 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’t 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 ‘yellow,’ we are seeing light in that 550-ish nanometers range. But we don’t have a cone in our eyes that can pick that up. Your brain just has a very consistent guess about what color that wavelength of light could be. We decided to name that guess ‘yellow.’ We can’t imagine what yellow really looks like any more than a dog can imagine the color red.

Here’s the funny thing: your brain is never perceiving just one photon of light at a time. Something like 2*10⁸ photons per second are hitting your retina under normal conditions. Your brain doesn’t 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, “yeah, that cup is blue, fuck it, next.”

That’s 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 “yellow.” 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’ve 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’s more red than green, we’ll call that ‘orange.’ Literally who gives a shit, we’re trying to forage over here. There are bears out here and it’s so scary.

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

Fucking green.

Hey, that’s not gonna work? We live on a planet where EVERYTHING IS GREEN. If something is NOT green, that means it’s 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’ll just make up another color. Something that looks really, really different from green. 

And so it made up magenta.

So, physics-wise, is magenta “real?”

No; there’s no single wavelength of light that corresponds to magenta. But you’re 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:

Explaining this thing is a little more than I want to take on on a Saturday morning, but I’ve included a link above that goes into it a little more. The point is that only the colors that actually touch the ‘outline’ of the shape actually correspond to a specific wavelength of light. All of the other colors are blends of multiple wavelengths. So magenta isn’t 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’s just as real as most of what we see. It’s 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’t. Because it’s not green. Light that’s green has a wavelength of around 510 nm. Stuff that’s 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.

Yall.

Just be a rock.

shower. not a bath, a shower. use water as hot or cold as u like. u dont even need to wash. just get in under the water and let it run over you for a while. sit on the floor if you gotta.

moisturize everything. use whatever lotion u like. unscented? dollar store lotion? fancy ass 48 hour lotion that makes u smell like a field of wildflowers? use whatever you want, and use it all over. 

put on clean, comfortable clothes. 

put on ur favorite underwear. cute black lacy panties? those ridiculous boxers u bought last christmas with candy cane hearts on the butt? put em on.

drink cold water. use ice. if u want, add some mint or lemon for an extra boost.

clean something. doesn’t have to be anything big. organize one drawer of ur desk. wash five dirty dishes. do a load of laundry. scrub the bathroom sink. 

blast music. listen to something upbeat and dancey and loud, something that’s got lots of energy. sing to it, dance to it, even if you suck at both.

make food. don’t just grab a granola bar to munch. take the time and make food. even if it’s ramen. add something special to it, like a hard boiled egg or some veggies. prepare food, it tastes way better, and you’ll feel like you accomplished something. 

make something. write a short story or a poem, draw a picture, color a picture, fold origami, crochet or knit, sculpt something out of clay, anything artistic. even if you don’t think you’re good at it.

go outside. take a walk. sit in the grass. look at the clouds. smell flowers. put your hands in the dirt and feel the soil against your skin.

call someone. call a loved one, a friend, a family member, call a chat service if you have no one else to call. talk to a stranger on the street. have a conversation and listen to someone’s voice. if you can’t, text or email or whatever, just have some social interaction with another person. even if you don’t say much, listen to them.

How exactly does it work if I…if I do come over to you? I mean, how - how is it better for me when I tell my wife, whom I love, and this family, that I’m turning against them? How?
