ART is Rhapsody's perceptual model. How ART works
What kind of blue is Regal Blue?
Every color has a place in the standard vocabulary. This is Regal Blue's, measured rather than asserted.
Regal Blue's Munsell numbers: hue 3.3PB, value 2.5 (how light), chroma 6.6 (how vivid). That places it in ISCC-NBS block dark blue, one of 267 named ranges the standard sorts every color into. Chroma 6.6 is low. This is a greyed, muted blue, nearer neutral than vivid, which is why it reads as a surface rather than an accent.
There's still some room before it hits the edge of what your screen can show for this hue. It could go a little more saturated and stay in gamut.
Munsell coordinates and block from the ISCC-NBS system, computed by Rhapsody's own renotation inversion.
