Incandescent Light Color Spectrum. Thus a relatively low temperature emits a dull red and a high temperature emits the almost white of the traditional incandescent light bulb. The basis for light sources used as the standard for color perception is a tungsten incandescent lamp operating at a defined temperature.
When a piece of metal is heated the color of light it emits will change. Color temperature is a description of the warmth or coolness of a light source. As long as the scene we are viewing contains a continuous spectrum of colors we interpret the light as white.
An incandescent lamp s light is thermal radiation and the bulb approximates an ideal black body radiator so its color temperature is essentially the temperature of the filament.
