ART is Rhapsody's perceptual model. How ART works

What kind of neutral is Mine Shaft?

Every color has a place in the standard vocabulary. This is Mine Shaft's, measured rather than asserted.

Mine Shaft is achromatic. That means no hue at all. Its red, green, and blue channels are equal, so there's no direction for a hue to point in. Only lightness. Munsell writes that as value 2.1 with chroma 0 (chroma is how vivid a color is). ISCC-NBS, the naming standard built on top of Munsell, files it under black.

Because there's no hue to reproduce, a neutral is the one kind of color that survives almost any conversion unchanged. No gamut (the range of colors a screen or a press can actually show) can clip a hue that isn't there.

Munsell coordinates and block from the ISCC-NBS system, computed by Rhapsody's own renotation inversion.
