The Science Behind Indigo:

Indigo’s position on the color spectrum is due to its unique wavelength and light absorption properties. It has a frequency range of approximately 445-464 terahertz, making it a shorter-wavelength color compared to blue but longer than violet. This specific frequency range affects human perception and distinguishes indigo from its neighboring colors.

Furthermore, color psychologists suggest that indigo can stimulate the production of serotonin, a neurotransmitter associated with feelings of well-being and happiness. This may explain its calming and stress-relieving effects.


Indigo is more than just a color; it holds historical, cultural, and psychological value. From its origins in natural dyes to its modern-day applications, indigo captivates us with its rich hue and deep symbolism.
