my reasoning: the actual colors we can see -> the wavelengths that we can extrapolate to -> basically extrapolated wavelengths plus an 'unpure-ness' factor -> not even real wavelengths (ok well king blue and maybe lavender if I'm being generous could be)

"not even wavelengths" bitch you never heard of ultraviolet? It literally the wavelength.

[–] AdrianTheFrog 28 points 3 weeks ago (3 children)

look at this chart, and look for the pink. It isn't there, because pink isn't real

I should have excluded king blue and violet tho, those are actually real, mb

look at this guy who only understands hue LMAO

light has three parts that are needed to define color. hue, saturation, luminance. the difference between orange and brown is saturation. a thing that affects color visually undeniably. you can't just throw a hue chart at us and pretend the other parts don't exist.

you can achieve this result through rgb color mixing by controlling percentages. for example magenta is going to be like 50% red. and 50% blue. pink is just 20% red. your chart only shows colors at 100% intensity and additive mixing. color behaves differently whether you're mixing light or pigments. light will combine to create white. you literally have to combine the different frequencies. this is additive mixing and where rgb is used. there is also subtractive mixing where color is defined by what frequencies are reflected and which are absorbed. when you mix all the colors together this way you get black, because all frequencies will be absorbed. this method uses ryb as its primaries.

so this all really depends on whether we're looking at additive or subtractive. you seem to be a little confused on your color swatches there. following additive mixing, like you seem to be, you should say white is real and black isn't. though neither is true. they're just 100,100,100 and 0,0,0 respectively.

I'll start by saying the computer rgb and hsl models are an abstraction matching how we perceive light that doesn't include any other spectral information that we can't see

in terms of wavelengths of light, pink is not a hue, unlike other fully saturated colors it does not have a wavelength to go along with it

yes, you can combine red and blue to make pink, but then you're looking at the wavelengths of red and blue and not those of pink (because pink doesn't have a wavelength)

any color that isn't red, green, or blue could be any one of an unlimited number of spectrums that would produce the same perceived result, but any fully saturated color other than pink does have one single wavelength that goes along with it

like I said above, hue is analogous to wavelength, saturation is analogous to the 'unpure-ness' of the wavelengths, and value/luminance is analogous to the quantity of those wavelengths - and pink is one that breaks this pattern

the difference between orange and brown is saturation.

It’s weirder than that. The difference between orange and brown is context

Violet is, but I'm not sure the color labeled violet here actually is.

White is.. impure? And the disrespect for minerals... No no no this won't do at all, I am coming over and burning all of your pudding (a fitting punishment)

Combos of red and blue are blends of wavelengths.

🤓 ☝️ Actually black and white are shades, not colours.

[–] Kushan 4 points 3 weeks ago

So is brown. Brown is dark orange.

[–] AdrianTheFrog 3 points 3 weeks ago

I guess the hue and maybe saturation are undefined there according to most color models (HSL would have hue and saturation undefined for white but HSV would only have hue undefined)

Try wrapping your head around colors used in taxonomic keys for a bit.

[–] Eheran 5 points 3 weeks ago (3 children)

Can we have a picture with correct white balance? So we can actually see the colors?

Imagine taking about colors without the technique by which they are produced.

Also, did you just call black a real color when you are talking about wavelengths?

The problem with your statement is (not) fully understanding how our brains work at interpreting colors.

You mentioned yellow in this thread - our brains (not our eyes) see two different colors that they device to interpret as yellow, which is different to seeking a true yellow wavelength.

More of an everyday example of that is "white" (found under your mental illnesses) - you can buy cheap light bulbs that cover a smaller fraction of the light spectrum or better ones with high CRI numbers ("photographers lights"). I recently installed them in my parents house & they are amazed.

The other thing is we never ever see just one exact wavelength in nature, we have to mix and interpret all of them in other to make quick decisions & survive.

Evolutionary in our own line the red ones was the last addition, presumably to pick the red fruit quicker.

Also when you mention monitors (that emit light), they do all kinds of fuckery like pixel dithering where you mix two "colors" shown by the same subpixel (or two) but in a rapid succession.

Beige babies are the manifestation of middle class ennui.

[–] [email protected] 5 points 3 weeks ago (1 children)

I don't think this makes sense, all colors are real... except the mental illnesses, beiges and sepias.

[–] AdrianTheFrog 5 points 3 weeks ago (3 children)

well these ones specifically are displayed on your monitor (which can only display red, green, and blue) so they actually aren't real

your eyes are being tricked into thinking there's yellow for example, when there's really only red and green, this is because we can't really see yellow, we can just guess that its there based on the relative red-ness and green-ness of the light

However, it is very lucky for monitor manufacturers that we're so easily 'fooled'

[–] [email protected] 10 points 3 weeks ago (1 children)

That’s not really true, we can definitely see yellow light. Red receptors and green receptors are both sensitive to it, which your brain correctly interprets as yellow.

[–] AdrianTheFrog 1 points 3 weeks ago

yea, if there is a single wavelength and its yellow we could see it. However, if you had a full spectrum of light and took away all of the yellow but added some red and green you wouldn't be able to tell that there's no yellow, because we can't see yellow, only imply it from the red-ness and green-ness

i'm pretty sure you couldn't pull off the same trick with red, green, or blue but I guess I don't really know

[–] Eheran 2 points 3 weeks ago* (last edited 3 weeks ago) (1 children)

your eyes are being tricked into thinking there's [something]

That is what the brain does and it does it all the time with everything. You can have a simple B/W picture and you/your brain will see motion.

[–] angrystego 1 points 3 weeks ago (1 children)

That's not true though. Yellow is a very real wavelength. The fact that we don't have unique receptors for it changes nothing about it's nature. Also our eyes are not being tricked into anything, they just pass on the signal they get. Our brain sometimes plays tricks on itself. But interpreting red and green signal as yellow means getting closer to the physical truth, not further from it.

Isn’t violet / purple the made up one ?

[–] [email protected] 2 points 3 weeks ago

I think magenta is the made up one. But also apparently most colors are existentially weird in some way

[–] howsetheraven 5 points 3 weeks ago

Red and green are the same color, duh, dumbass.

Colorblind btw.
