Under warm 2700K interior light Bancha shifts subtly: drifts toward yellow; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1), so it is a lighting-stable choice.

Against white it measures 5.65:1 and against black 3.72:1, 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.
#babea2 · #949878 · #666a47 · #4d5030 · #2c2f13 · #101100
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.
#739374 · #6b8056 · #666a47 · #605625 · #574218 · #4a2f11
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.
#a9cabb · #74b197 · #6f8b7e · #666a47 · #4b4e23 · #31340a
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.
#cacdba · #a7ab8e · #868879 · #666a47 · #4a406d · #2b2e17
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f2f1f8 · #808278 · #666a47 · #4d4d52 · #1f2017 · #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.
#f1f3e5 · #c8cbba · #666a47 · #22240b · #040400 · #c4ce4e
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#c4dec2 · #93ce8e · #7298d1 · #666a47 · #3f4366 · #061015
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#f2efff · #6e81a5 · #666a47 · #613f65 · #0f1e3d · #030004
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#e4f5ff · #5c879f · #666a47 · #6d3b51 · #351022 · #00060f
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#66694E · #666955 · #66685C
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.
