Which tool helps maintain color accuracy in mixed lighting?

• A. Auto White Balance
• B. Telephoto lens
• C. Macro lens
• D. Gray card

Answer: (A)

Managing color temperature is about giving the camera a neutral reference when lighting is not uniform. In mixed lighting, different light sources (like tungsten and daylight) cast different tints, so colors can shift across the scene. A gray card provides a known neutral gray reference (about 18% reflectance). By metering or photographing the card and setting the white balance from that neutral reference, you lock in a consistent color balance for the shot. This keeps whites looking white and other colors accurate across different parts of the image and across sessions. Auto White Balance often tries to guess the scene’s overall tint, but with multiple light sources it can pick the wrong color cast, leading to inconsistent or biased colors. The lens type doesn’t fix color accuracy—telephoto and macro lenses affect framing, perspective, and depth of field, not the color cast caused by lighting. So using a gray card to set custom white balance is the reliable method for maintaining color fidelity in mixed lighting.
