Purple is a kind of red to me.

Depends on what shade of purple

intensely_human ,

Or what tint, or what hue.

MagicShel ,

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.

Tolookah ,

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 ,

Nu uh!

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

Surgically, 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 ,

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.

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

deadbeef79000 ,

First one, then the other

Lukewarm purple?

Idfk, for me almost everything with visible blue in it is blue.

It depends on the definition of purple.

intensely_human ,

purple is when your eyes are about to cry with joy

xilliah ,

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

Skua ,

It's anti-green

intensely_human ,

Anti yellow

intensely_human ,

Depends on the purple

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