Under warm 2700K interior light Fern 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.
#9bf0b6 · #66ca8a · #009b54 · #007c42 · #00532a · #002e14
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.
#28beb1 · #00ad87 · #009b54 · #428225 · #556800 · #565100
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.
#00d8ea · #62aeb7 · #009b54 · #007940 · #00582d · #00363c
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.
#cff5d9 · #9bd6ad · #8eac96 · #009b54 · #923885 · #1c4f30
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#fbedf8 · #8fa394 · #009b54 · #6e646c · #1c3022 · #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 · #009b54
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d8d9b4 · #7da370 · #009b54 · #8d1977 · #3d375e · #130624
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#eac5db · #d66f8e · #009b54 · #5b4b6b · #2d3c5c · #051311
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#edf1ff · #8596e9 · #009b54 · #ae3c24 · #540a00 · #010011
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

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.
