Under warm 2700K interior light Quercitron shifts subtly: drifts toward orange; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.3), so it is a lighting-stable choice.

Against white it measures 1.98:1 and against black 10.61:1, 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.
#fff0d4 · #e5b03d · #cb9928 · #9f7500 · #735300 · #4a3400
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.
#dde892 · #e1cd67 · #e5b03d · #dd9542 · #ce7d4b · #ba6854
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.
#e5b03d · #88a478 · #9e7404 · #397002 · #593f00 · #183204
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.
#ebdbbe · #e5b03d · #af935f · #3c65b9 · #4b3501 · #2a1c00
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#ebf2ff · #e5b03d · #a69c8a · #5a5f68 · #2f2513 · #000104
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.
#ecf2fd · #c2c9d6 · #949caa · #1a2233 · #00030f · #e5b03d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d1d8b3 · #e5b03d · #c89377 · #268ae4 · #2a3964 · #051215
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#afddd3 · #e5b03d · #af96d8 · #405b72 · #2e3856 · #101204
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#d2fbfe · #e5b03d · #22b1bc · #833e8c · #400548 · #000203
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#DCB362 · #D3B57D · #CAB795
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.
