Under warm 2700K interior light Mustard shifts subtly: leans toward orange; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.4), so it is a lighting-stable choice.
#d3ae00 — ΔE 1.4, shifts subtly: leans toward orange#d4b300 — ΔE 0.9, shifts subtly: leans toward orange#ceb301 — ΔE 0.0, is virtually unchanged#ceb406 — ΔE 0.2, is virtually unchangedAgainst white it measures 2.08:1 and against black 10.07:1, 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.
#fff3b7 · #e3ca46 · #ceb301 · #907c00 · #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.
#beea92 · #c5d05c · #ceb301 · #cd9600 · #c57b1c · #b56430
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.
#ceb301 · #70a27b · #897600 · #006d30 · #4a3f00 · #002f10
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.
#ded7b4 · #ceb301 · #9f9251 · #4e4fb5 · #3e3400 · #201a00
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#eef1ff · #ceb301 · #9c9882 · #595a65 · #2a260e · #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 · #030210 · #ceb301
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#cadab7 · #ceb301 · #89a875 · #1e73b7 · #2b3963 · #041115
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#b5ddf0 · #ceb301 · #899ec0 · #824aa3 · #2a3755 · #140b04
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ddf7ff · #ceb301 · #00a8c9 · #902d79 · #460038 · #000408
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#C8B44D · #C2B46F · #BCB48A
Its chroma is high enough to carry accents, calls to action, and focal moments; large fields of it will dominate a composition. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
