Color cast can be observed as:

• A. A post-processing sharpening technique
• B. A color cast is a subtle tint of one color that makes colors look off
• C. A lens distortion artifact
• D. A color space conversion method

Answer: (B)

Color cast is a subtle tint of one color that makes colors look off. This happens when the lighting or color temperature in a scene dominates, causing whites and neutrals to shift and other colors to drift toward that tint. You’ll notice it in indoor photos that look amber or yellow under tungsten lighting, or in shade where everything takes on a cool blue cast, or under certain fluorescent lights that give a greenish cast. Recognizing color cast helps explain why white balance is essential: adjusting it toward the neutral point or using a gray card lets whites read as truly white and keeps other colors accurate. To fix it, you can set the correct white balance in-camera or adjust it later in post-processing, using a neutral reference to guide the correction. It’s not about sharpening, which affects edges, nor about lens distortion, which warps geometry, nor about color space conversion, which maps colors between spaces without describing a scene-wide tint.
