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.
#81b4cd · #548eab · #126180 · #004660 · #002535 · #000810
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.
#adafd0 · #8b8cc7 · #71738f · #126180 · #00445d · #00293a
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.
#d29674 · #697b85 · #126180 · #1e4050 · #052331 · #000a12
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f9f0eb · #a5b2b9 · #77716d · #126180 · #36434a · #050201
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.
#faefea · #d4c8c1 · #ab9d95 · #37271e · #140601 · #126180
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d7d4af · #87b8ad · #f53635 · #126180 · #58394b · #030f28
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffeee5 · #d99f9d · #8d6d32 · #126180 · #622f30 · #110700
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffecf4 · #d39eb6 · #757737 · #126180 · #43440d · #060002
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. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
