Difference of color and brightness in an image.

Difference of color and brightness in an image.

• A. Contrast
• B. Hue
• C. Saturation
• D. Temperature

Answer: (A)

The concept being tested is how lightness differences across an image are described. Contrast controls the difference in brightness between bright and dark areas, making details pop or recede. A high-contrast image has stark whites and deep blacks, while a low-contrast image looks flatter with more midtones. Hue, saturation, and temperature describe color properties rather than the range of brightness: hue is what color something is, saturation is how vivid the color is, and temperature is the warmth or coolness of the overall color cast. So the term that best captures differences in color and brightness together is contrast, which directly governs how distinct bright and dark regions appear.
