Color cast in an image refers to:

• A. A subtle tint of one color, generally red, green or blue, that causes an image to appear unrealistic.
• B. A phenomenon where all colors are perfectly balanced
• C. A digital filter that sharpens edges
• D. A color profile used for printing

Answer: (D)

Color cast is an overall tint of the image toward a single hue, usually due to lighting conditions or an incorrect white balance. This bias shifts all colors in the scene so the image begins to look unrealistic or off-naturnal. It isn’t about balance being perfect, nor about a filter sharpening edges, nor about how colors are managed for printing. The tint toward red, green, or blue describes color cast precisely, because it shows that the entire image leans toward that color due to light or camera settings. To prevent or correct it, adjust white balance in the camera or fix it in post-processing, often by neutralizing the tint with white balance tools or by using a gray card as a reference at the scene.
