Hue Curves

Target hue, saturation and luminance along hue curves.

Hue curves let you retouch colour the way a finishing artist isolates a range: shift greens, quiet magentas, lift luminance in a narrow band. They are more surgical than a global hue slider.

Useful for product colour, foliage and skin when only one region should move.
