Nonsense.
It’s science.
“Nonsense”
Absolutely NOT nonsense.
Red and blue make PURPLE and one color ( red ) is much longer than the other ( blue); so that statement is 100% false.
OTOH...beets are NOT any shade of purple; they're a shade of RED! Yet there they are in the photo. And those grapes are mostly deep shades of red!
I paint ( I'm a watercolorist and also know about pigments ), so I'm very atuned to colors, shades, and variations of colors. Violet is a shade of PURPLE ( there are many different shades of all colors! ) so....IF violet IS a "color", then so is purple and it has nothing at all to do with our brains mixing colors to make a different one.
“Nonsense.”
I’ll go one better - Balderdash!
People only exist in our minds. Yeah, sure. When we’re not looking at them, they don’t exist. They don’t affect the world at all.
Thank you. My thoughts exactly
Thanks for posting this. I work in color science and this article is for the most part correct, but the author makes a few confusing statements along the way. All perceived colors are made up by the brain, not just purple. Spectral colors (the colors of the rainbow) are the colors we see when the light falling on the cone cells is from a narrow band of wavelengths. Purple is not a spectral color because it cannot be perceived by stimulating the cone cells with a single narrowband light source, but requires at least two narrowband wavelengths at opposite ends of the spectrum, one that stimulates the short wavelength cone cells and the other that stimulates the long wavelength cone cells. Violet (as defined by color scientists) and which most people perceive as similar to purple in color is perceived when only the short wavelength cone cells are being stimulated.
