Under warm 2700K interior light Beach Dune shifts subtly: drifts toward orange; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.7), so it is a lighting-stable choice.

Against white it measures 1.91:1 and against black 10.99:1, so black text is the stronger pairing. That pairing passes WCAG AA for body text. Avoid white text on this color entirely.
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.
#fbf1d6 · #c6bb9c · #aca285 · #857c63 · #615942 · #3e3724
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.
#d8e6bc · #d2d19e · #c6bb9c · #c3a377 · #b48d6f · #a37968
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.
#c6bb9c · #8fa38d · #8c7d51 · #476c45 · #52441c · #20311e
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.
#e4dfcf · #c6bb9c · #a3997d · #4a5884 · #433b24 · #252011
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#eff2f9 · #c6bb9c · #a39f95 · #5e6065 · #2b271d · #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.
#f6f2e6 · #c6bb9c · #4e4734 · #312a17 · #100900 · #e6c04d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#edf1ff · #c6bb9c · #919ec6 · #505e8b · #1c2547 · #090400
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#edf1ff · #c6bb9c · #7ea5c2 · #675684 · #002b43 · #020006
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#e2f6fa · #c6bb9c · #72aab5 · #795074 · #391b36 · #000305
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#C4BBA3 · #C1BBAA · #BFBBB0
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.
