Hue

Hue refers to the specific color aspect of an object, determined by its wavelength in the visible spectrum. It’s what differentiates red from blue, green from yellow. Think of hue as the "color family" or the dominant color that the eye perceives. It is one component of color, alongside others like saturation (intensity) and brightness (lightness or darkness). When adjusting hue in digital images or paints, you change this fundamental color characteristic, shifting the overall color appearance without affecting its saturation or brightness.
