Against white it measures 8.58:1 and against black 2.45:1, 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.
#9b9da5 · #757880 · #494c55 · #31343c · #14161d · #010103
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.
#4d738c · #435e82 · #494c55 · #3a365f · #342447 · #2a1430
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.
#b19bb3 · #9b76a0 · #736175 · #494c55 · #263052 · #101735
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.
#d6c38c · #838ba3 · #666b78 · #494c55 · #282e45 · #111521
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f4f2ea · #a5a8b3 · #676560 · #494c55 · #31343e · #010100
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.
#f0f2f6 · #c7c9cd · #494c55 · #202228 · #020307 · #e5c04d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#f7f2e1 · #b7a87e · #75642f · #494c55 · #413304 · #000007
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#f7f2e1 · #c5a183 · #5f6c39 · #494c55 · #4c2c0d · #010100
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffedea · #cc9b92 · #43724f · #494c55 · #183e23 · #050000
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#3D3F47 · #31333A · #25272D · #1A1C21 · #0F1115
Its moderate chroma lets it work in mid-size areas — upholstery, secondary UI surfaces, editorial blocks — without overwhelming neighbors. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
