Under warm 2700K interior light Cactus shifts subtly: drifts toward yellow-green; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.2), so it is a lighting-stable choice.

Against white it measures 5.45:1 and against black 3.85:1, so white text is the stronger pairing. That pairing passes WCAG AA for body text.
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.
#b2c3ad · #8a9d85 · #5b6f55 · #43553d · #24331f · #081505
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.
#679786 · #598668 · #5b6f55 · #505e30 · #4b491d · #43360e
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.
#a6ccc9 · #69b3af · #6c8d8b · #5b6f55 · #3a5532 · #22391a
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.
#c1d3bc · #a07eaa · #5b6f55 · #444d41 · #23321e · #0d160b
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f5f0f6 · #7e857c · #5b6f55 · #514e52 · #1c221a · #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.
#ecf5ea · #c2ccbf · #5b6f55 · #192715 · #000500 · #97d982
The same quiet ground carrying one bright gold voice — the high-energy pairing a cool or muted anchor cannot reach through its own temperature.
#ecf5ea · #c2ccbf · #5b6f55 · #192715 · #000500 · #f4b84d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#f9edfc · #92779a · #5b6f55 · #614169 · #2d1533 · #000200
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#f9edfc · #817da5 · #5b6f55 · #6d3d56 · #201a3c · #040001
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#eaf2ff · #6d84a7 · #5b6f55 · #733d3f · #391114 · #000007
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#5E6E59 · #616C5D · #646B61
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.
