Aura colors
Aura colors are read as moods and temperaments: blue as communication, red as drive, green as care. We checked all 31 that people search for against the visible spectrum, and 19 of them do not exist as light at all.
Checked against the visible spectrum
19 of the 31 aura colors are not colors of light
Why pink and magenta have no wavelength
The visible spectrum runs from about 380 nanometres to 750 — violet at the short end, red at the long one. Every color in that range can be produced by one frequency of light. Pink cannot. There is no wavelength for pink: the eye receives red and blue together with no green between them, and the brain produces a color to represent that combination. The same is true of magenta, which sits opposite green, in the gap where red and violet would meet if the spectrum were a circle.
White, black, gray, gold, silver and brown
Others fail for different reasons. White is every wavelength at once, black is none, gray is all of them dimmed equally. Gold and silver are not hues but reflections — surface properties, not light. Brown only exists in contrast: the same light that reads brown against a pale background reads orange against black.
What this does and does not prove
This does not disprove anything about auras. A color can be perceptually real and physically constructed at the same time — pink is not an illusion, it is a genuine perception with no single frequency behind it. What it does mean is that a claim to see a pink aura is a claim about perception, not about detectable light, a distinction aura guides rarely make.

All 31 aura colors
Blue is looked up 548 times more often than the rarest color here. Wavelength shown where one exists.
Interest and physics barely overlap: only 4 of the 10 most searched aura colors exist as a wavelength.

Where aura color meanings come from
“The table of colours given in the frontispiece has already been thoroughly described in the book _Man Visible and Invisible_, and the meaning to be attached to them is just the same in the thought-form as in the body out of which it is evolved.”
“The brilliancy and the depth of the colours are usually a measure of the strength and the activity of the feeling.”
What aura photography captures
Kirlian photographs, 1939
Kirlian photography records corona discharge, an electrical effect around an object in a high-voltage field. It varies with moisture, pressure and voltage, which is why a freshly washed hand photographs differently from a dry one.
Aura cameras
Modern aura cameras do something else entirely: hand sensors measure skin conductance and temperature, and software assigns colors from a lookup table someone chose. The colors are generated, not photographed, which is why the same person can get different results on two machines.
Aura readers under test
In a 1997 screen test by Gissurarson and Gunnarsson, ten aura readers had to say which of four screens hid a person. They picked the right one 185 times, where blind guessing predicts 180. That does not make the color vocabulary worthless as a way of describing mood; it means it is describing, not measuring.
