Indigo is contested in physics: Newton named seven colours to match the seven notes of a scale, and many modern accounts drop indigo as a separate band entirely. It survives in the chakra system as the third eye, so a colour included for musical symmetry became a spiritual category.

Light and dark indigo
These two are not symmetrical, and it goes the opposite way to how it looks. Dark indigo is the same wavelength with less light — still pure. Light indigo is that wavelength plus every other one, because white is all of them. The pale version is the mixed version.
Light indigo
Adding white light, which means adding every other wavelength alongside the 445–464 nm band. So a light indigo aura is, in physical terms, less purely indigo than the standard one — the hue is diluted, not brightened. Read as perception that arrives before the reasoning held more lightly.Dark indigo
The identical wavelength at lower intensity — fewer photons, same frequency. Dark indigo is therefore the only one of the two that is still purely indigo: nothing has been added to it, only removed. Read as certainty without a way to check it — the strained version.Questions about the indigo aura
What does a indigo aura mean?
Perception that arrives before the reasoning. The shadow side is certainty without a way to check it.
Is indigo a real colour of light?
Yes. It occupies 445–464 nanometres of the visible spectrum — 19 nm out of the roughly 370 the eye can see — so a single frequency of light produces it.
Which chakra is indigo?
The Third eye chakra. Only 8 of the 31 colours people search for as auras map onto a chakra at all — the system covers seven positions, not the whole palette.
How rare is a indigo aura?
Unanswerable — auras are not counted anywhere. What is countable is interest: 1,640 searches a month, rank 26 of 31.
