What kind of teal is Aero Blue?

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

Aero Blue's Munsell numbers: hue 6.2G, value 9.6 (how light), chroma 7.3 (how vivid). That places it in ISCC-NBS block brilliant green, one of 267 named ranges the standard sorts every color into. Chroma 7.3 is moderate. Clearly colored, but not so saturated it fights the colors around it.

It's already at the edge of what your screen can show for this hue. This color can't go any more saturated and still render.

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

Is Aero Blue 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. Black text on #C9FFE5 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 · 66 of 210 pairings reach WCAG 2.2 AAA, shown here.

Aero Blue in CMYK: one value for files, one per press

None of these presses can print this color. It's lighter than the paper, and ink only darkens a sheet, so the brightest thing on a printed page is the page itself. So what do you do? Pick a brighter stock, or let the paper be your lightest tone and build the contrast somewhere else.

In CMYK, #C9FFE5 is C21.2 · M0 · Y10.2 · K0. That is the value design tools and file formats use when no press is involved.

On press (what each standard prints)

Press values computed through the ICC characterization data each standard proofs against. Each CMYK above is the closest that standard can get. None of them reaches the color. It sits above the paper's own white.
