I’ve never come across an adequate definition for the color “red”, at least as a qualia though I have little doubts that the color “red” exists (definable or not).

visible red light is an electromagnetic wave that has a wavelength of about 650 nm.

“visible red light is an electromagnetic wave that has a wavelength of about 650 nm.”

I knew that response would come up and that’s why I specifically referred to the *qualia* of the color “red” which is totally different.

Sorry.
