Hue
Hue describes the color family of an image color, such as red, green or blue. A hue adjustment shifts colors around that color cycle, rather than simply making them more saturated or brighter.
BetterDisplay can apply a software hue adjustment where the chosen image-processing method supports it. A hue shift changes the image's colors; it does not select a new display color profile or calibrate the panel.
See Saturation, Image Adjustments and Apple's hue-filter documentation.
