Checked against the visible spectrum

Red is a real color of light

Wavelength 620–750 nm
Width of the band 130 nm of the visible 370
Chakra Root — one of only 8 covered
Lightness of the swatch L* 49 of 100
Purity of the swatch 55% of a spectral color

The longest visible wavelength — beyond 750 nanometres is infrared, which we feel as heat rather than see. Fitting for the root chakra and a reading about the body, survival and force.

What a red aura is said to mean

Red is read as physical energy, passion and drive — the color of the root chakra and of survival. Bright, clear red is described as vitality, courage and a strong will; dark or muddy red as anger, frustration or stress held in the body. Red people are said to act first and think second, and to be at their best when there is something to fight for.

The reading

Physical energy, drive and appetite

The shadow side

Anger held close to the surface

Primary source

The red aura in the first published color key

Besant and Leadbeater, 1905
“Red, of all shades from lurid brick-red to brilliant scarlet, indicates anger; brutal anger will show as flashes of lurid red from dark brown clouds, while the anger of “noble indignation” is a vivid scarlet, by no means unbeautiful, though it gives an unpleasant thrill…”
Annie Besant and C. W. Leadbeater, Thought-Forms (London, 1905), “The Meaning of the Colours” — read the original text. Besant and Leadbeater repeat the key from Leadbeater’s Man Visible and Invisible (1903), the book that popularized the idea of a colored aura. Most modern aura charts descend from Christopher Hills’s rainbow scheme of 1977, which is why their meanings often differ.

The red aura in everyday life

In love

Passionate, direct and intense. A red partner shows love through action and can flare up quickly — and calm down just as fast.

At work

Sport, entrepreneurship, emergency services and any job that rewards energy and quick decisions.

Finding balance

Readers suggest a physical outlet for the energy and a pause before reacting — the count to ten exists for red.

Light and dark red

Adding white more than halves the purity of red, from 55% to 19% in #E1999C (L* 70), because white is every wavelength at once. Adding black barely touches it: #6F2729, at L* 27, keeps the hue and almost all of the purity.

Light red · #E1999C · L* 70

Read as a softer form of the same reading: physical energy, drive and appetite.

Dark red · #6F2729 · L* 27

Read as anger held close to the surface — the strained version.

Questions about the red aura

What does a red aura mean?

Physical energy, drive and appetite. The shadow side is anger held close to the surface.

Is red a real color of light?

Yes. Red occupies 620–750 nanometres, 130 nm of the roughly 370 the eye can see. No other aura color's band overlaps even half of that range.

Which chakra is red?

The root chakra. It is one of 8 aura colors out of 31 that map onto a chakra at all.

How rare is a red aura?

Auras have never been counted, so rarity cannot be measured. Interest can: red sits between yellow and orange in searches, 10th of 31 colors at 4.4%.
