ART is Rhapsody's perceptual model. How ART works

What kind of violet is Darkblue?

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

Darkblue's Munsell numbers - the industry way of describing hue, value (how light), and chroma (how vivid) - come up one short. Value reads 1.0. Hue and chroma don't, because the reference data behind that math thins out at the very light and very dark ends of the scale, and at value 1.0 it runs dry before the math converges. Printing a hue or chroma here would be invented, not measured, so Rhapsody leaves them blank. ISCC-NBS, the standard built on top of Munsell that sorts every color into one of 267 named ranges, still places this one in deep purplish blue, by its nearest match.

Nothing else on this page leans on that missing number. The tonal scale, the pairings, and the press comparison below all come from separate measurements, and they land on Darkblue just fine. It's the notation that runs dry here, not the color.

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

Is Darkblue accessible? Contrast with white & black

Strong contrast makes your work readable by everyone, and meets the WCAG standard accessibility law points at. AA is the floor; AAA is the tier worth aiming for in body text. White text on #030764 clears WCAG AAA. Every strip below is one surface, and the marks are the steps that reach AAA on it.

Rows are text, columns are background · 70 of 210 pairings reach WCAG 2.2 AAA, shown here.

Darkblue in CMYK: one value for files, one per press

This color shifts further than a press run can hold, so expect a visible difference. The pairs below show where each standard lands.

In CMYK, #030764 is C97 · M93 · Y0 · K60.8. That is the value design tools and file formats use when no press is involved.

The complementary color, straight across the wheel, is a warm pale gold #E0CD8D. Rhapsody's pick is the split complement, just to one side of it, a livelier pair.

The accent is for the moments that need attention, the harmony for the ones that need calm; the neutral carries the text and surfaces in between.
