Spectral color         
A spectral color is a color that is evoked in a typical human by a single wavelength of light in the visible spectrum, or by a relatively narrow band of wavelengths, also known as monochromatic light. Every wavelength of visible light is perceived as a spectral color, in a continuous spectrum; the colors of sufficiently close wavelengths are indistinguishable for the human eye.

SPECTRAL SEQUENCE RELATING THE SINGULAR COHOMOLOGY OF THE TOTAL SPACE OF A SERRE FIBRATION IN TERMS OF THE COHOMOLOGIES OF THE BASE SPACE AND THE FIBER
Leray-Serre spectral sequence; Leray–Serre spectral sequence; Spectral sequence for the covering
In mathematics, the Serre spectral sequence (sometimes Leray–Serre spectral sequence to acknowledge earlier work of Jean Leray in the Leray spectral sequence) is an important tool in algebraic topology. It expresses, in the language of homological algebra, the singular (co)homology of the total space X of a (Serre) fibration in terms of the (co)homology of the base space B and the fiber F.

  • The power spectrum of the measured [[cosmic microwave background radiation]] temperature anisotropy in terms of the angular scale. The solid line is a theoretical model, for comparison.

The spectral edge frequency or SEF is a measure used in signal processing. It is usually expressed as "SEF x", which stands for the frequency below which x percent of the total power of a given signal are located.

Spectral color

A spectral color is a color that is evoked by monochromatic light, i.e. either a single wavelength of light in the visible spectrum, or a relatively narrow band of wavelengths (e.g. lasers). Every wavelength of visible light is perceived as a spectral color; when viewed as a continuous spectrum, these colors are seen as the familiar rainbow.

All colors that do not qualify as a spectral color are called non-spectral colors or extra-spectral colors. Extra-spectral colors cannot be evoked with a single wavelength of light, but rather by a combination of wavelengths. Likewise, light comprising several wavelengths cannot evoke a spectral color.
