At the lower end of the scale, from 2000K to 3000K, the light produced is called “warm white” and ranges from orange to yellow-white in appearance.
Color temperatures between 3100K and 4500K are referred to as “cool white” or “bright white.” Light bulbs (lamps) within this range will emit a more neutral white light and may even have a slightly blue tint.
Above 4500K brings us into the “daylight” color temperature of light. Light bulbs (lamps) with color temperatures of 4500K and above will give off a blue-white light that mimics daylight.
