Against white it measures 12.66:1 and against black 1.66:1, so white text is the stronger pairing. That pairing passes WCAG AA for body text. Avoid black text on this color entirely.
One color explored: close hues with real lightness and chroma structure, so the palette is the anchor through value rather than a set of colors.
#9ea0a3 · #797b7e · #55575b · #313337 · #16181b · #020203
The anchor's neighbours on the wheel — everything shares an undertone, so the chord carries color without anything having to be muted to get along.
#2f586e · #244564 · #313337 · #1f1f45 · #1a0e2f · #11021a
The mid-gap pairing — sage and mustard, terracotta and olive. A foil rotated 40–65° toward warm or cool: too far to be kin, too near to argue, carried by temperature and a deliberate value offset.
#af9db6 · #7486ab · #7a5b86 · #56475b · #313337 · #0b1938
One deliberately opposed voice — a single restrained counterpoint across the wheel, or temperature against temperature where the anchor is too muted to carry a loud opposite.
#dbc18c · #646f85 · #4a505d · #313337 · #0f182b · #01030b
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f5f1ea · #b2b6c0 · #817e79 · #464b55 · #313337 · #201d17
This color as a ground rather than a subject — its own restraint held across a narrow value band, carrying one saturated voice from the opposite temperature.
#f1f2f4 · #cfd0d2 · #a9abad · #5b5c5f · #313337 · #eebc4d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#f9f1e1 · #c8b48b · #937b48 · #5b481e · #313337 · #141d2f
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#f9f1e1 · #d6ad93 · #7d844e · #654128 · #313337 · #1d1f09
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffedeb · #daa8a4 · #628a62 · #345434 · #313337 · #2c1614
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

As a deep tone it works for grounding elements — text, outlines, and shadowed surfaces — rather than open fields.
