Against white it measures 6.48:1 and against black 3.24:1, so white 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.
#b1b1b1 · #8b8b8b · #5e5e5e · #454545 · #252525 · #090909
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.
#7b875f · #747243 · #5e5e5e · #64471e · #573419 · #462315
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.
#aabfa7 · #7fa57a · #6f816c · #5e5e5e · #504115 · #352700
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.
#c8c1af · #a99e82 · #6c7cab · #5e5e5e · #454033 · #2c240e
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#eff2f9 · #b7b3a8 · #76787d · #5e5e5e · #49453b · #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 · #5e5e5e · #222222 · #030303 · #e7c04d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#edf2ff · #a4b2da · #6676a5 · #5e5e5e · #384468 · #0b0500
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#edf2ff · #91b9d6 · #7f6e9e · #5e5e5e · #224a64 · #020006
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#e1f6fa · #86bec8 · #91688d · #5e5e5e · #593956 · #000305
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#4e4e4e · #3f3f3f · #2f2f2f · #1f1f1f · #101010
Its moderate chroma lets it work in mid-size areas — upholstery, secondary UI surfaces, editorial blocks — without overwhelming neighbors.
