What kind of blue is Dirty Blue?
Every color has a place in the standard vocabulary. This is Dirty Blue's, measured rather than asserted.
Dirty Blue's Munsell numbers: hue 7.6B, value 5.0 (how light), chroma 5.8 (how vivid). That places it in ISCC-NBS block moderate greenish blue, one of 267 named ranges the standard sorts every color into. Chroma 5.8 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.
