The adjustment also produces a relatively stable unique red (3), an extraspectral hue at right angles to unique yellow, where it limits the neutralizing effect of "blue" light in "warm" (red, orange and yellow) hue perception.

So when you take extraspectral colors into consideration, this doesn't show every color we can see right? But this does? ... Some editing tools change the hue or saturation while you change lightness. Luminosity Blend Mode doesn't preserve chromaticity. Some color spaces don't preserve chromaticy, either, such as in CIELAB...
