About the Visible Light Spectrum

Visible light is the portion of the electromagnetic spectrum that human eyes can detect, ranging from approximately 380 nm (violet) to 750 nm (red). Each wavelength corresponds to a specific color perception.

Shorter wavelengths appear blue/violet, while longer wavelengths appear orange/red. This tool converts any wavelength within the visible range to its approximate RGB representation for design and educational purposes.
