The standard used to measure the reddishness or bluishness of white light is called

• A. White Balance
• B. Color Temperature
• C. Brightness Level
• D. Color Gamma

Answer: (B)

Color temperature is the measure used to describe how warm (reddish) or cool (bluish) white light appears. It’s expressed in kelvin and reflects how the light would look if it came from a perfect black-body radiator at that temperature. Lower temperatures, around 2700–3200 K, give warm, orange-red tones; higher temperatures, 5000–6500 K and above, yield cooler, blue tones. This scale helps photographers and videographers set white balance so whites look white under different lighting. Brightness level concerns how bright the light is, not its color cast, and color gamma deals with how displays map brightness to color. So the standard for reddishness or bluishness is color temperature.
