Correlated Color Temperature (CCT) can be defined as the color of white light a light source is emitting. CCT is measured in Kelvin (K). The different color temperatures along the Kelvin scale correlate with different shades of white light, all of which impact how an individual perceives the space. LED lights are typically grouped into 3 different color temperatures: warm white, natural white, and cool white. Warm white gives off a yellow shade of light, natural light closely resembles the color of light given off from the sun, and cool light has a slightly blue tint to it.
