ART is Rhapsody's perceptual model. How ART works

What kind of orange is Cinnabar?

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

Cinnabar's Munsell numbers: hue 7.5R, value 5.1 (how light), chroma 14.9 (how vivid). That places it in ISCC-NBS block vivid reddish orange, one of 267 named ranges the standard sorts every color into. Chroma 14.9 is about as saturated as named colors get. Nothing muted shares this block.

It reaches 78% of the way to the edge of your screen's gamut (the palette a screen can actually show) for this hue. Strong, with some headroom left before the screen runs out.

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