Against white it measures 9.82:1 and against black 2.14:1, 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.
#b0b1b1 · #8a8b8a · #656766 · #424443 · #242525 · #080909
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.
#386f70 · #1f6056 · #424443 · #194122 · #1e320e · #1f2300
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.
#9cc0ca · #76a690 · #418799 · #46646d · #424443 · #003322
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.
#b7cbc1 · #b6829f · #56665e · #424443 · #112e22 · #00130a
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f7eff3 · #9ca7a1 · #605a5d · #424443 · #242f2a · #020101
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.
#f1f2f1 · #cbcccc · #a2a3a2 · #424443 · #0f1010 · #e356b0
The same quiet ground carrying one bright gold voice — the high-energy pairing a cool or muted anchor cannot reach through its own temperature.
#f1f2f1 · #cbcccc · #a2a3a2 · #424443 · #0f1010 · #f2ba4d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#feecf5 · #c095ac · #7a4a66 · #424443 · #421e34 · #000301
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#feecf5 · #b299be · #814a4e · #424443 · #382242 · #090001
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#f0f0ff · #9f9fc9 · #7f4e37 · #424443 · #46210f · #010007
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#373938 · #2c2d2d · #212222 · #161716 · #0b0b0b
Its moderate chroma lets it work in mid-size areas — upholstery, secondary UI surfaces, editorial blocks — without overwhelming neighbors.
