CCT - COLOR TEMPERATURE OR COLOR TEMPERATURE

CCT refers to the color temperature of light, measured in degrees Kelvin (K). The temperature rating directly affects how white light will look - it ranges from cool white to warm white.

For example, a light source in the 2300-3000K range is considered what we call warm white light. Warm white light looks a little orange or yellow. As Kelvin increases, the color changes from yellow to yellowish white to white to bluish white (which is the coldest white).

Although the different temperatures have different names, they should not be confused with real colors such as red, green, or purple. CCT is specific to white light, or rather color temperature.
