Which tools can use hue and saturation to select an area of an image?

• A. Color Wheels
• B. Color Warper
• C. Qualifier
• D. Color Warper and Qualifier

Answer: (D)

The key idea is isolating parts of an image based on color properties. The Qualifier is the direct tool for this: it lets you define a pixel range by hue and saturation (and luminance) and then create a mask that selects exactly those areas. You can sample colors with an eyedropper and then tighten the Hue and Saturation ranges to capture precisely the region you want.

The Color Warper isn’t a selection tool by itself, but it works with color values to map or remap hues across the image. In practice, you can use it to fine-tune how the colors within a selected region are shifted or transformed, which often pairs with a qualifier to shape the final result of the hue/saturation-based area you’ve isolated. So, together they cover the workflow of identifying by hue/saturation and then transforming that region.
