What's worth owning?
Tangent from Bryan
"Within a Japan Aerospace Exploration Agency clean room in the Tokyo suburb of Sagamihara, engineers complete the attachment of the Extreme Ultraviolet Imaging Spectrometer, one of three telescopes for studying the sun, to the Solar-B spacecraft. The spectrometer is the long black box on the bottom. "
Colors; how many are there?
I posit that there are as many colors as there are wavelengths in the entire light spectrum.
Human eyes can only see a fraction of the entire light spectrum (visible) and even then, our eyes and brains are not sophisticated enough to discern colors of say, one wavelength in difference.
So we "see" only a small fraction of the colors that exist.
But that's making the assumption that color is something that exists outside of our perception of it.

"A reasonable working definition of color is that it's our human response to different wavelengths of light. The color isn't really in the light: We create the color as a response to that light, just as we create the sensation of pain when struck by an object."
Bruce Fraser
Color is a reaction? Does everything have the potential of color, then?
Wiki sez: "color is a perceptual property"
But wiki is not written to scientific standards. Not sufficiently specific and lazy word use.
"Color or colour[1] is the visual perceptual property corresponding in humans to the categories called red, yellow, blue, black, etc."
So, do animals not see color? Also, are infrareds and ultraviolets considered colors? (many animals are able to perceive these spectra)
Colorimetry, huh?
Still no answer to my question. Internet, you are so vast.
No more time for wormholes today. Work to do.
