A number of studies have found sunlight can have a multitude of benefits on our health. It turns out cooler light makes workers more productive. So, according to science and experts, what color temperature lighting is most beneficial in a work setting? An overcast winter day is measured at about 7,000K and is considered a cool color.A typical sunny day is about 5,000K or 5,500K and is considered a cool color.A sunset is about 4,000K and is considered a cool white color.The glow-from-the-fire lighting is about 2,000K and is considered a warm color.Lower color temperatures (up to 3,000K) range from red to yellowish-white in tone and are called warm colors.įor a better idea, Felderman and Keatinge gave some examples of what these color temperatures look like in everyday life: Mid-range color temperatures (3,100K–4,600K) appear cool white.
Higher color temperatures (4,600K or more) appear blue-white and are called cool or daylight colors. Lower color temperature light sources are called “warm” because they emit red, orange and yellow color, whereas higher color temperature light sources are called “cool” because they are on the violet and blue end of the color spectrum.īelow is a rundown of the color temperatures in light sources: As the temperature increases, the horseshoe will start to glow different colors from red, then orange, then yellow, then white, and, finally, it will emit a bluish-white color.
Just take, for example, a blacksmith heating up an iron horseshoe. As the temperature increases, the object changes colors and emits certain colors of that light. Temperature of light, measured in Kelvin (K), is a numerical measurement of the color that’s emitted when an object is heated in a high enough temperature. For those unfamiliar with lighting temperatures and colors, what do they mean?
