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

Against white it measures 2.18:1 and against black 9.65:1, 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.
#fff1cc · #e7c66b · #cfac47 · #977917 · #6e5600 · #463600
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.
#cce198 · #cdc86f · #cfac47 · #c89243 · #bb7a45 · #aa654a
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.
#cfac47 · #7c9b78 · #8c7016 · #26671f · #4b3a00 · #0c2b09
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.
#ddd3b8 · #cfac47 · #9f8d5d · #3e539f · #3e3003 · #1f1600
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#edf2fe · #cfac47 · #9a9483 · #565961 · #2a2413 · #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.
#edf2fd · #c4c9d6 · #969baa · #1c2233 · #01020f · #cfac47
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#cfd9b5 · #cfac47 · #c98c79 · #217bd4 · #26345c · #061013
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#aededc · #cfac47 · #a785d3 · #4e6278 · #2b3553 · #0d1003
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#d8f9ff · #cfac47 · #36a5b6 · #7f3b7a · #3e073c · #000305
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.
#d8fbf3 · #cfac47 · #3fa896 · #3e539e · #490023 · #010010
#D7B864 · #DFC47D · #E7D095 · #EEDCAD · #F6E9C4
#AB8C2E · #896D12 · #675000 · #463500 · #271C00
#C8AD64 · #C2AF7B · #BBAF90
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.
