Under warm 2700K interior light Duck Butter shifts subtly: leans toward orange; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.6), so it is a lighting-stable choice.

Against white it measures 1.69:1 and against black 12.39:1, 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.
#fff3b9 · #ddc75b · #b7a23d · #8f7d1b · #685900 · #423800
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.
#d9e293 · #ddc75b · #daab4e · #d1914c · #c37a4f · #b06553
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.
#ddc75b · #8ab391 · #9a882e · #207f40 · #5c4f00 · #143f20
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.
#f1ebce · #ddc75b · #afa570 · #8d8355 · #4f54a6 · #2e280b
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#ddc75b · #a7a9b6 · #7b7766 · #45474f · #211d0b · #010104
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.
#eff1fd · #c6c8d6 · #999baa · #1f2233 · #030310 · #ddc75b
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#ddc75b · #a4a8c3 · #6970b3 · #3a3b8b · #150e4e · #070400
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ddc75b · #a4a8c3 · #407bb1 · #5b2e7c · #001e39 · #05000f
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ddc75b · #8fb0ba · #00859f · #71245f · #38002d · #000407
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#D8C777 · #D3C78F · #CEC7A5
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.
