Against white it measures 5.08:1 and against black 4.13:1, 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.
#c1c2da · #9a9bb6 · #6b6c89 · #51526c · #313248 · #141426
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.

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.
#ca9abe · #9c8496 · #6b6c89 · #4e4e75 · #343456 · #2c1827
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.
#ccc78e · #8d8e9d · #6b6c89 · #4d4d66 · #303146 · #171724
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f3f2ea · #888993 · #6b6c89 · #565651 · #22222c · #010100
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.
#f0f1fd · #c7c7d6 · #6b6c89 · #202033 · #030210 · #d5c84e
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#f4f3e2 · #908c61 · #6b6c89 · #5d5721 · #282400 · #010007
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#f4f3e2 · #a08461 · #6b6c89 · #455f32 · #331e00 · #000100
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffeee7 · #a97e6c · #6b6c89 · #27634a · #002b1b · #0c0100
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#6C6D84 · #6D6D7E · #6D6E79
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.
