Adjustment layers can make color adjustments to an image without permanently changing the pixel values.

• A. True
• B. False
• C. Only for grayscale images
• D. They require flattening to apply

Answer: (A)

Adjustment layers provide non-destructive color adjustments. In Photoshop, an adjustment layer sits above the image (or a group of layers) and applies its effect to everything beneath it without altering the underlying pixel values. The actual image data stays intact, and the adjustment’s parameters are stored on the layer, so you can tweak, reorder, mask, or delete it at any time and revert to the original appearance if desired. This non-destructive workflow is why the colors can be adjusted without permanently changing pixels. The other options don’t fit: color adjustments on adjustment layers aren’t limited to grayscale images, and you don’t have to flatten the image to apply them—flattening would merge layers and remove the non-destructive capability. If you later want a permanent result, you can merge layers or apply the adjustment layer, but that’s an explicit step beyond the default non-destructive behavior.
