Understanding Color Temperature 


What is Color Temperature? 

Color Temperature is a term used to describe the color of a given light.

It is based on the color given off by a glowing hot piece of platinum.

For instance, heat the metal to "red hot" and its temperature describes the red color.

Heat it more and you get "yellow hot," "white hot," eventually even "blue hot." 

The Kelvin Temperature Scale 

Color temperature is always measured in degrees Kelvin.

The Kelvin scale is the temperature scale normally used in physical sciences like astronomy.

It is like the more familiar Fahrenheit or Celsius scales, except 0º on the Kelvin scale

is Absolute Zero - the temperature at which there is no heat energy left in an object.
