Hue-vs curves (HSL curves)

Hue-vs curves are the HSL curves that target a range of hues and adjust one property of only those hues. Hue-vs-hue rotates the chosen hues toward a neighbor (swing yellows warmer, or peel greens away from browns); hue-vs-sat saturates or desaturates them; hue-vs-lum brightens or darkens them. You set goalposts — a left and right control point that bracket the target hue — then move the point between them, keeping the goalposts’ rotation at zero so neighbouring hues stay untouched. Presets tend to drop the goalposts too wide (choke them in) and the eyedropper too narrow (widen out). They belong to the broader curves family and are a gentler, less artifact-prone alternative to a hard qualifier.
