This is for the newbes in reef keeping, hope this will help:
The appearance of your animals depends upon the color of the lighting used in the aquarium. The color tone of any light source is classified in terms of its temperature and expressed in degrees Kelvin. A candle flame is a very warm light source with a low color temperature of abgout 1,800 K, wheras midday sunlight in the tropics is about 6,500 K. Lamps running at higher color temperatures (10,000 K, 14,000K and even up to 20,000 K and higher) give out a harsher, colder, bluer light as the color temperature increases. Warm lights make reds and yellows look good, whereas the colder lights give the fish a much paler rendition. However, it must be said that these are the colors you would acturally preceive in the sea, where only the blue end of the light spectrum penetrates to any great depth.
-tungsten lamps are 2,500 - 3,000 K Warm light.
-cool white flourescent are 4,000 K white.
-normal daylight is 6,500 K.
-A clear blue sky is 10,000 - 30,000 K.
