Determination of luminous color gamut of continuous emissions in visible waveband
Regarding objects of monotonic emissivities in the visible waveband, the concept of color-kernel body is put forward. With this concept, the luminous color of actual objects is found out to be the mixture of the radiative colors of a blackbody and a color-kernel body with different weights. The locus of the isothermal radiative colors is a straight-line segment in the chromaticity diagram. The whole color gamut of continuous emissions is about 17% of the entire gamut of natural colors and at its bottom.
