What controls the intensity of colors in a photo?

• A. Brightness
• B. Saturation
• C. Hue
• D. Sharpness

Answer: (B)

Saturation controls the intensity of colors in a photo. It measures how pure or vivid a color is—the amount of gray mixed in. When saturation is increased, colors become more vibrant and punchier. When it’s decreased, colors fade toward gray and look muted. This is different from brightness, which changes how light or dark the image appears overall, regardless of color purity. Hue is about which color you’re seeing (red, blue, etc.), not how strong the color is, and sharpness affects edge clarity rather than color strength. In practice, adjusting saturation lets you make colors pop or tone them down to keep a natural, accurate look in commercial work.
