What does kelvin mean?


Kelvin is a description of colour temperature (warmth or coolness) of a light globe. The colour spectrum emitted by globes begins as red then graduates to orange, yellow, white, blue-white and then darker shades of blue. The kelvin measurement corresponds to these colours. 

At sunrise the red sun approximately 1,800 Kelvin. As it rises the sun goes from red to orange, orange to yellow an then peaks at white around noon, at which point it is about 5,000 Kelvin.  As the sun sets the colour changes again to more red and orange hues the Kelvin drops accordingly.
