Against white it measures 10.83:1 and against black 1.94:1, 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.
#9b989e · #76737a · #535057 · #3f3c43 · #151218 · #010102
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.
#535c80 · #4c4770 · #3f3c43 · #3e2143 · #32122b · #240514
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.
#c9a7b2 · #9b8ab1 · #996275 · #6a5059 · #3f3c43 · #2c1b3d
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.
#b9cd98 · #80768d · #5e5866 · #3f3c43 · #271d32 · #0c0712
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f0f3ec · #bdb8c3 · #858782 · #58535e · #3f3c43 · #252822
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.
#f2f1f4 · #cbc9cd · #a09ea2 · #3f3c43 · #09070c · #aed464
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#eef5e5 · #b2c298 · #7c8f5c · #4e5c34 · #3f3c43 · #2b2236
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#eef5e5 · #c6bb8f · #619473 · #61552a · #3f3c43 · #172c1f
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#fdefe2 · #d6b393 · #4c958c · #24615a · #3f3c43 · #342312
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#353239 · #2B292E · #222024 · #19171B · #100E12
Its moderate chroma lets it work in mid-size areas — upholstery, secondary UI surfaces, editorial blocks — without overwhelming neighbors.
