Saturation controls which aspect of an image?

• A. Brightness
• B. Sharpness
• C. Color intensity
• D. Hue

Answer: (C)

Saturation describes how vivid or muted colors appear. It controls the presence of colorfulness in an image—the intensity of the color itself. A highly saturated color is bold and pure, while a desaturated color looks more gray and washed out. This is different from brightness, which changes how light or dark a color is without altering its vividness; it’s also different from hue, which determines which color family you’re looking at (red, blue, green, etc.). In practice, adjusting saturation changes the overall punch of the colors: boosting saturation makes reds, greens, and blues look more intense, while reducing saturation moves colors toward grayscale.
