Under warm 2700K interior light Kelly Green shifts subtly: leans toward yellow-green; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.5), so it is a lighting-stable choice.

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.
#a8f1be · #77cb93 · #339c5e · #147f46 · #00572c · #003216
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.
#4dbfb3 · #34af8b · #339c5e · #4d8437 · #586c0e · #595400
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.
#28dbed · #70b0b8 · #339c5e · #247b48 · #005c2f · #003a40
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.
#d7f7df · #a5d8b4 · #94af9b · #339c5e · #914385 · #275136
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#faedf7 · #95a699 · #339c5e · #71686f · #1f3125 · #020002
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.
#f9eef6 · #d1c4ce · #a597a2 · #2c1c29 · #090107 · #339c5e
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d5d7b2 · #80aa75 · #339c5e · #a31c41 · #463250 · #200803
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#b4daf0 · #b18d9a · #339c5e · #60429b · #2d3b57 · #04100f
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#edf1ff · #8b9ce4 · #339c5e · #aa4833 · #560a00 · #010011
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#4D9867 · #609370 · #6F8E78
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.
