Visible Continuous Color Spectrum

The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye.

Electromagnetic radiation in this range is called VISIBLE LIGHT, or simply LIGHT.

A typical human eye will respond to wavelengths between 380 to 750 nm (Nanometers)

An eye that has adapted to daytime conditions generally has a maximum sensitivity around 555nm. Compared to the color red which optical spectrum is around 630 – 650nm our eye is closer to the Green region of the optical spectrum at 510 - 530nm.
