Convert light wavelength in nanometers to its corresponding RGB color. Explore the visible light spectrum from violet to red with instant color preview and hex codes. Pure client-side.
Visible range: 380–750 nm
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.
