Color temperature is described by correlated color temperature (CCT) and is expressed in Kelvin; higher Kelvin means cooler light.

• A. Higher Kelvin means warmer light
• B. Higher Kelvin means cooler light
• C. Kelvin measures brightness
• D. Kelvin is unrelated to color

Answer: (B)

Color temperature describes the color appearance of white light and is expressed as correlated color temperature in Kelvin. As the Kelvin value rises, the light shifts toward the blue end of the spectrum, so it appears cooler. Lower Kelvin values produce warmer, more amber light. So the statement that higher Kelvin means cooler light is correct. Remember, Kelvin measures color, not brightness (brightness is measured in lumens). This helps you choose appropriate lighting for different spaces, with warmer tones for residential areas and cooler tones for work environments.
