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 ( @deadbeef79000@lemmy.nz ) 16•2 months ago
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.
- intensely_human ( @intensely_human@lemm.ee ) 9•2 months ago
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.

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.

Purple is a green wavelength that doesn’t trigger the green cones in your eyes.
It is made up by your brain.
- intensely_human ( @intensely_human@lemm.ee ) 2•2 months ago
Exactly

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.
- Tolookah ( @Tolookah@discuss.tchncs.de ) 3•2 months ago
Nu uh!
Okay, poor choice of words by me. Wavelength color vs what the eyes see.
- ddh ( @DarkDarkHouse@lemmy.sdf.org ) English2•2 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.

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

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 ( @idiomaddict@feddit.de ) 2•2 months ago
I’m not trying to be a jerk here, but what’s an example of a warm blue? I can’t imagine it.
- Elise ( @xilliah@beehaw.org ) 2•2 months ago
- idiomaddict ( @idiomaddict@feddit.de ) 2•2 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.

Depends on the purple
- Scrubbles ( @scrubbles@poptalk.scrubbles.tech ) English8•2 months ago
Depends on what shade of purple
- intensely_human ( @intensely_human@lemm.ee ) 2•2 months ago
Or what tint, or what hue.
- Stepos Venzny ( @SteposVenzny@beehaw.org ) English5•2 months ago
I’m colorblind and purple is often just blue without any qualifiers.
- wright ( @wright@beehaw.org ) 3•2 months ago
Purple is red; violet is blue.
