Because the hue scale was designed to be perception-based, so flipping by 180 is the intended use. Obviously a single formula cannot describe all complexity of human color perception, especially if you take into account spatial interactions and background illumination.
The color science is far from developed, and better models than HSV and CIELAB are available, but typically are very complex with little practical gain.
- klodolph 6y agoThe hue scale is not designed to be based on perception. It is simply a polar coordinate version of RGB.
- hanche 6y agoEven that is an approximation: The hue is piecewise linear instead of using trigonometric functions. Linear, that is, in each 60° sector. (Or affine for the super pedantic.)
