A few years later, following the work of Max Planck, the radiation from platinum was replaced with the radiation from a black body (full radiator), which was more universal.

The value of the new candle is such that the brightness of the full radiator at the temperature of solidification of platinum is 60 new candles per square centimetre.[9]

Black Body Displays a palette based on the different colors a blackbody radiator emits as it is heated—from black to red, orange, yellow, and white.

Emissivity is defined as the ratio of the energy radiated by an object at a certain temperature to the energy emitted by a perfect radiator, or blackbody, at the same temperature.
