‘Colour temperature’ is a classification of the colour of light that scales from warmer to cooler colours. The scale is measured in Kelvins with the higher Kelvin ratings being signified by the ‘cooler’ lighter, bluer colours, and smaller (K) ratings by ‘warmer’ reds, oranges and yellows. William Kelvin in 1880 first discovered that when you apply various levels of heat to carbon an array of colours is produced. He learnt that temperatures of 2500-3200K to a block of carbon a dim, dense reddish glow was produced, which gradually changed to lighter blue-white glows as the temperatures he applied increased between 4000-6000K.
Three common colour temperatures are warm white (2700K), cool white (4000K), and daylight white (6000K). Remember, so called warm and cool lighting are referred to as such because of their physiological characteristics and not because of their temperature. Find out below which colour temperature is best suited to which environment.
Warm White (2700K)
This classification of light appears warmer and therefore more appropriate for welcoming and relaxing living spaces such as living rooms, bedrooms or commercial spaces like restaurants, lounges and bars. Candle light is measured at 1500K so this colour grade is a modest warmth of light appropriate for domestic settings and hospitality orientated commercial spaces.
Cool White (4000K)
Emitting a cooling white light, this colour temperature is best suited to busy environments like kitchens, workplaces and offices where having a clear light source is important. It is also appropriate for corridors and store cupboards, as well as commercial buildings and classrooms.
Daylight White (6000K)
Daylight white produces a sharp artificial daylight colour that proves useful in busy environments such as kitchens, workplaces, receptions and offices. It is also suited for use in industrial warehouses, musuems or other environments where large spaces need illuminating.
When choosing the most effective outdoor lighting it is important to bare in mind any harmful side-effects your lighting may cause. Understanding colour temperature will help minimise the effects of artificial light sources on the aesthetic of your outdoor area and will help you harness the natural light of the surroundings effectively. Warmer colour temperatures are more effectively used on solid structures, often with the effect of emphasising impressive architecture or overstating the grandeur of a building, and cooler colour temperatures best mimic natural light so can be most effective when used as down lighting to illuminate shrubbery or flowerbeds.
