Against white it measures 3.59:1 and against black 5.85:1, so black text is the stronger pairing. That pairing passes WCAG AA for body text.
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.
#dfdfdf · #b7b7b7 · #878787 · #6c6c6c · #4a4a4a · #2a2a2a
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.
#a5b289 · #9e9c6c · #878787 · #8e6f46 · #805b3f · #6f493a
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.
#99ac96 · #878787 · #78683d · #355831 · #403208 · #10200e
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.
#f9efd4 · #d6cbae · #aea899 · #878787 · #495784 · #312c1d
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#eff2f9 · #a6a298 · #878787 · #6b6d72 · #302d23 · #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 · #878787 · #222222 · #030303 · #e7c04d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#edf2ff · #94a1c9 · #878787 · #5c6b99 · #212b4d · #0b0500
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#edf2ff · #80a8c5 · #878787 · #736392 · #043049 · #020006
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#e1f6fa · #75adb7 · #878787 · #865d82 · #3e203c · #000305
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#717171 · #5a5a5a · #444444 · #2d2d2d · #171717
Its moderate chroma lets it work in mid-size areas — upholstery, secondary UI surfaces, editorial blocks — without overwhelming neighbors.
