To me, It depends on the shade of purple

[–] [email protected] 35 points 4 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.

[–] [email protected] 26 points 4 months ago* (last edited 4 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.

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.

[–] [email protected] 5 points 4 months ago

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

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

[–] [email protected] 3 points 4 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.

[–] [email protected] 12 points 4 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!

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.

Fun fact: blends of colours are also colours.

[–] [email protected] 8 points 4 months ago (1 children)

Nu uh!

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

[–] [email protected] 2 points 4 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?"

[–] [email protected] 2 points 4 months ago

obviously it is D-flat C-sharp sucks.

[–] [email protected] 18 points 4 months ago

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

[–] [email protected] 15 points 4 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

Depends on the purple

[–] [email protected] 10 points 4 months ago (1 children)

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

[–] [email protected] 2 points 4 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.

[–] [email protected] 2 points 4 months ago (1 children)
[–] [email protected] 2 points 4 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.

[–] [email protected] 9 points 4 months ago (1 children)

Depends on what shade of purple

[–] [email protected] 2 points 4 months ago

Or what tint, or what hue.

[–] [email protected] 8 points 4 months ago

It depends on the purple.

Anti yellow

[–] [email protected] 6 points 4 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?

[–] [email protected] 5 points 4 months ago

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

[–] [email protected] 4 points 4 months ago

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

[–] [email protected] 3 points 4 months ago

Finally some important questions!

[–] meanmon13 3 points 4 months ago (2 children)

Is 0 nothing or the sum of all numbers?

Purple is a kind of red to me.

[–] [email protected] 2 points 4 months ago

There are a lot of shades that people call purple image

[–] [email protected] 1 points 4 months ago

Purple is red; violet is blue.

[–] [email protected] 2 points 4 months ago
[–] [email protected] 2 points 4 months ago (1 children)

It depends on the definition of purple.

[–] [email protected] 2 points 4 months ago

purple is when your eyes are about to cry with joy

[–] [email protected] 2 points 4 months ago

Lukewarm purple?

[–] [email protected] 1 points 4 months ago* (last edited 4 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
