Against white it measures 2.43:1 and against black 8.63:1, so black text is the stronger pairing. That pairing passes WCAG AA for body text. Avoid white 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.
#f2f2f2 · #c9c9c9 · #a6a6a6 · #7c7c7c · #595959 · #383838
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.
#c6d3a9 · #bebc8a · #a6a6a6 · #ae8e63 · #9f785b · #8e6555
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.
#a6a6a6 · #7b8e79 · #79693e · #365932 · #403208 · #10210e
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.
#f7ecd1 · #cfc9b9 · #a6a6a6 · #8e8469 · #495784 · #2f2a1b
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#eff2f9 · #a6a6a6 · #8e8a81 · #525358 · #252218 · #010102
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.
#f2f2f2 · #c9c9c9 · #a6a6a6 · #222222 · #030303 · #e7c04d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#edf2ff · #a6a6a6 · #7c89b0 · #43517d · #161f40 · #0b0500
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#edf2ff · #a6a6a6 · #6990ac · #5a4a77 · #00253b · #020006
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#e1f6fa · #a6a6a6 · #5e959f · #6b4467 · #321530 · #000305
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#8a8a8a · #6f6f6f · #535353 · #373737 · #1c1c1c
Its moderate chroma lets it work in mid-size areas — upholstery, secondary UI surfaces, editorial blocks — without overwhelming neighbors.
