How does your eye perceive the color white? When Red, Blue, Green light are added
together in equal proportions.
What is the color black? absence of light
What is correlated Color Temperature? Color temperature is the approximate quantification
of the color of "white" light, as rated on a numerical scale. Low color temperature light
(~2000K) has a warm (red-ish) look while light with a high color temperature (~6000K) has a
colder (blue-ish) appearance.
What is Color Temperature measured in? Kelvin
What is Candle Light on the Kelvin scale? 1900K
What is a high pressure sodium lamp on the kelvin scale? 2200K
What is a Tungsten lamp on the kelvin scale/ 3200- 3400K

as that of the image being viewed, allowing the eye to perceive color accurately.
