Conceptually, color temperature refers to the color of light emitted by a light source, a measurement of color itself, usually measured in Kelvin (K). It describes how "warm" or "cool" the light appears to the human eye.
Specifically, it is divided into:
Warm light (2000K-3500K) appears to have a yellowish or amber hue, often associated with comfort and relaxation.
Neutral light (3500K-4500K) strikes a balance between warm and cool colors and is ideal for task lighting in the kitchen or bathroom.
Cool light (4500K-6500K) appears bluish-white, mimicking natural daylight, which can enhance focus and visibility and is often used in office or photography settings.
