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.
As long as there’s not fifty shades of purple.... I’m good.
“This is ridiculous and worse, is the claim that NO LONG and SHORT WAVE LENGTH MAKES A COLOR!”
That was not stated in the article. You get an F in reading comprehension.
You may know colors but you know nothing about how we process colors.
Read the article and learn.
> Red and blue make PURPLE
You’re wrong, like almost every painter.
Red + Blue = Magenta.
“...there is no color ON THE SPECTRUM that’s created by combining long- and short-wavelength cones.”
Purple is not a Spectral Color. Spectral Colors are single frequency/wavelength. Mixing different frequencies produces colors that are not in the spectrum, just like mixing different frequencies of sound produces melodious tones or screeches like fingernails on a chalkboard........

I don’t think you know what a shade is ...
