To me, It depends on the shade of purple

[–] MagicShel@programming.dev 35 points 3 months ago (2 children)

Yes.

Purple is not a single color. Maybe a spectrum analysis could answer this for a given instance of purple, but that's not my area of knowledge.

[–] deadbeef79000@lemmy.nz 26 points 3 months ago* (last edited 3 months ago) (7 children)

Specifically, purple is not a wavelength, unlike red(s) at ~700nm and blue(s) at ~400nm.

Purple is what human eyes see when the blue and red cones are both stimulated by their respective colours of light.

[–] AFKBRBChocolate@lemmy.world 11 points 3 months ago (1 children)

I like that some people are so confident in their incorrect understanding of something that they'll downvote the correct answer.

What you said is correct.

[–] deadbeef79000@lemmy.nz 5 points 3 months ago

Urgh, I go to sleep, wake up, read soooooo much awful wrongness.

Thanks for the vote of ~~confidence~~ fact.

[–] intensely_human@lemm.ee 3 points 3 months ago (3 children)

Nope. Purple is a wavelength that partially triggers both the red and blue cones.

The visual spectrum is continuous, not just three wavelengths corresponding to the three cones.

The blue cones and the red cones are stimulated by purple light. It’s a mix of blue and red signals from the retina, but the light is a single wavelength that is actually purple.

[–] stealth_cookies@lemmy.ca 12 points 3 months ago

No, purple is a non spectral colour meaning it is incorrect to call it "a wavelength" but rather you say it is a perception of multiple wavelengths. Not that this is special, pretty much everything you see is a non-spectral colour.

This is the best in depth scientific explanation here, and deserves more upvotes. Thanks, was a nice read!

[–] Honytawk@lemmy.zip 4 points 3 months ago (1 children)

Purple is a green wavelength that doesn't trigger the green cones in your eyes.

It is made up by your brain.

Right, indigo is a color (~425nm), violet is a color (~400nm), purple is typically a blend of colors.

[–] DarkDarkHouse@lemmy.sdf.org 9 points 3 months ago (1 children)

Fun fact: blends of colours are also colours.

[–] Tolookah@discuss.tchncs.de 8 points 3 months ago (1 children)

Nu uh!

Okay, poor choice of words by me. Wavelength color vs what the eyes see.

[–] DarkDarkHouse@lemmy.sdf.org 2 points 3 months ago

No worries, sorry for the snark. I find colour fascinating, like, when you dream of a purple dinosaur that's colour without any light at all.

"Would you consider the middle to be closer to one side, or the other?"

[–] oo1@lemmings.world 2 points 3 months ago

obviously it is D-flat C-sharp sucks.

[–] Binette@lemmy.ml 18 points 3 months ago

That's kind of like saying if 1 is 0 + 1 or 2 - 1

[–] Corno@lemm.ee 15 points 3 months ago (1 children)

Depends on the shade! There are warmer purples that are closer to red, and cooler purples that are closer to blue

All colors have cold and warm variants and can work in surprising ways when used in color compositions.

[–] idiomaddict@feddit.de 2 points 3 months ago (1 children)

I’m not trying to be a jerk here, but what’s an example of a warm blue? I can’t imagine it.

[–] xilliah@beehaw.org 2 points 3 months ago (1 children)
[–] idiomaddict@feddit.de 2 points 3 months ago

That warm blue does look cozy, in that it looks like the color that your dad’s old too-short shorts were in the 70s.

[–] intensely_human@lemm.ee 10 points 3 months ago

Depends on the purple

[–] scrubbles@poptalk.scrubbles.tech 9 points 3 months ago (1 children)

Depends on what shade of purple

[–] intensely_human@lemm.ee 2 points 3 months ago

Or what tint, or what hue.

[–] Etterra@lemmy.world 8 points 3 months ago

It depends on the purple.

[–] Skua@kbin.earth 7 points 3 months ago (1 children)
[–] intensely_human@lemm.ee 4 points 3 months ago

Anti yellow

[–] LordWiggle@lemmy.world 6 points 3 months ago

It's a different color, I consider it purple, my favorite part of the color spectrum. Purple can be made with both blue and red, but still is a completely different color. How would you consider water? Like liquid oxygen or wet hydrogen? Or just like water?

[–] SteposVenzny@beehaw.org 5 points 3 months ago

I’m colorblind and purple is often just blue without any qualifiers.

[–] DmMacniel@feddit.org 4 points 3 months ago

Purple is a group of colours in between of blue and red, but unlike Indigo is leaning toward red (hot).

[–] CyberMonkey404@lemmy.ml 3 points 3 months ago

Finally some important questions!

[–] meanmon13@lemmy.zip 3 points 3 months ago (2 children)

Is 0 nothing or the sum of all numbers?

[–] Double_A@discuss.tchncs.de 2 points 3 months ago (2 children)

Purple is a kind of red to me.

[–] AFKBRBChocolate@lemmy.world 2 points 3 months ago

There are a lot of shades that people call purple image

Lukewarm purple?

[–] nichtburningturtle@feddit.org 2 points 3 months ago (1 children)

It depends on the definition of purple.

[–] intensely_human@lemm.ee 2 points 3 months ago

purple is when your eyes are about to cry with joy

[–] wright@beehaw.org 2 points 3 months ago

Purple is red; violet is blue.

[–] olafurp@lemmy.world 1 points 3 months ago* (last edited 3 months ago)

Colors are very dependent on cultural context so if people would put their countries along with answers it'd be nice.

I personally think it's completely separate and not really comparable even though directly translated from Icelandic the color is "violet blue". From Iceland
