The following table shows the correlated colour temperature of common light sources:
|Tungsten Bulb (household variety)
|Sunrise/Sunset (clear sky)
|Daylight with Clear Sky (sun overhead)
|Moderately Overcast Sky
|Shade or Heavily Overcast Sky
Here is a visual representation of the Kelvin temperature scale. Notice how lower temperatures are very warm, and following the color spectrum, increase in numeric value as they become cooler.
