Against white it measures 5.22:1 and against black 4.03:1, 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.
#bbc3c6 · #949ca0 · #656e72 · #4c5458 · #2c3336 · #0f1518
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.
#649b9a · #4a8994 · #656e72 · #36607f · #354c6e · #32385a
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.
#9da4d8 · #8488a1 · #656e72 · #23576b · #063c4d · #191b30
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.
#b9d7e5 · #c89279 · #656e72 · #415057 · #173541 · #081920
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f8f0ec · #7e898e · #656e72 · #57524f · #192429 · #030100
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.
#eff2f4 · #c7cbcd · #656e72 · #252b2e · #050a0c · #f07b3d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#ffeee6 · #a67c68 · #656e72 · #75452e · #3a1603 · #00050b
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffeee6 · #a8787a · #656e72 · #6b4d1d · #3b1317 · #0f0500
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#feecf5 · #a2788e · #656e72 · #58551f · #262300 · #040002
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#535B5E · #41484C · #31373A · #212628 · #121618
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.
