Under warm 2700K interior light Neon Green shifts subtly: leans toward yellow, loses intensity; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 2.2), so it is a lighting-stable choice.

Against white it measures 1.36:1 and against black 15.49:1, 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.
#d7ffd1 · #39ff14 · #24c300 · #199700 · #0e6d00 · #044500
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.
#9bffc5 · #39ff14 · #a2d700 · #b6b600 · #b99900 · #b57d00
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.
#39ff14 · #00cecc · #20b500 · #008a88 · #0f6f00 · #004a4a
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.
#39ff14 · #da2ef6 · #527c4c · #0b6200 · #034000 · #002000
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#39ff14 · #c4b0c8 · #6e8a6a · #564858 · #082705 · #030005
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.
#f7eff8 · #cfc5d0 · #a397a4 · #2a1d2c · #08010a · #39ff14
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#eef1cb · #39ff14 · #acc78d · #f230a6 · #46385c · #1d0503
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffede6 · #39ff14 · #bebce4 · #b55794 · #423e5d · #111104
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.

Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

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.
