Against white it measures 6.02:1 and against black 3.49:1, 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.
#bbb5bb · #948f95 · #676168 · #4d484e · #2d282d · #100c10
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.
#8581a8 · #7e6b94 · #676168 · #6b4360 · #5d3445 · #4c252c
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.
#d7b4b6 · #c98c91 · #95787a · #676168 · #583c5d · #3c2340
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.
#aad1a4 · #8a7f8c · #676168 · #503e53 · #322334 · #150c16
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#eef4ed · #bab3bc · #7b7f7a · #676168 · #4f4751 · #010201
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.
#f3f1f4 · #cdcacd · #676168 · #2d292e · #0c080d · #90da86
The same quiet ground carrying one bright gold voice — the high-energy pairing a cool or muted anchor cannot reach through its own temperature.
#f3f1f4 · #cdcacd · #676168 · #2d292e · #0c080d · #e1c24d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#eaf6e8 · #a1c09c · #64895f · #676168 · #365332 · #030004
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#eaf6e8 · #b7ba8e · #4a8c78 · #676168 · #4c4e22 · #000402
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#faf1e1 · #cab38b · #3f8b90 · #676168 · #115559 · #0d0500
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

Its moderate chroma lets it work in mid-size areas — upholstery, secondary UI surfaces, editorial blocks — without overwhelming neighbors.
