What is Kelvin or Color Temperature of light?
This is simply the mixture of colors that is displayed. You can also equate this to the color knobs of a TV set. As you adjust these colors, the objects look either more yellow/red and or more blue/green. The research that has been been discussed above proves that colors that operate with enhanced blue lighting/scotopic qualities will look more vibrant and clear. Tech definition: A measure of the color of a light source relative to a black body at a particular temperature expressed in degrees Kelvin (K). Incandescent lights have a low color temperature (approximately 2800K) and have a red-yellowish tone; daylight has a high color temperature (approximately 6000K) and appears bluish (the most popular fluorescent light, Cool White, ia rated at 4100K). Today, the phosphors used in fluorescent lamps can be blended to provide any desired color temperature in the range from 2800K to 6000K.
