What is the relationship between the Kelvin temperature and the color of light emitted by an object?

The relationship between the Kelvin temperature and the color of light emitted by an object is that as the temperature increases, the color of the light emitted shifts from red to orange, then to yellow, white, and finally blue as the temperature gets hotter. This is known as blackbody radiation, where higher temperatures correspond to shorter wavelengths and bluer light.
