Colour temperature

Colour temperature refers to the hue of light emitted by a light source. It is a numerical measurement that describes the appearance of light based on its warmth or coolness. Colour temperature is measured in Kelvin (K).

When we talk about warm lighting in our homes, we often refer to the light produced by tungsten bulbs. Tungsten lighting typically has a color temperature of around 3600 Kelvin. This warm lighting is compared to "daylight," which typically has a higher colour temperature of between 5600-6500K and a bluer "white point".
