Under warm 2700K interior light Green Yellow shifts subtly: leans toward yellow; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 2.1), so it is a lighting-stable choice.
#bbf81a — ΔE 2.1, shifts subtly: leans toward yellow#b7ff25 — ΔE 1.0, shifts subtly: leans toward yellow#adff2f — ΔE 0.0, is virtually unchanged#acff32 — ΔE 0.1, is virtually unchangedAgainst white it measures 1.23:1 and against black 17.12:1, 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.
#adff2f · #97e40b · #79b800 · #5c8e00 · #416600 · #274100
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.
#adff2f · #cedb00 · #d8bb00 · #d79d00 · #d38000 · #ce6000
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.
#adff2f · #5adac8 · #79b800 · #009989 · #4b7500 · #00584e
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.
#adff2f · #b0c899 · #a944e3 · #436900 · #2c4700 · #162900
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#adff2f · #ccc0d5 · #819072 · #574f5e · #192707 · #020005
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.
#f5effa · #ccc6d2 · #a098a7 · #271e2e · #06010c · #adff2f
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#adff2f · #d5caa6 · #f634cd · #507158 · #323257 · #23060e
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#adff2f · #eac2b4 · #a47093 · #5d54bd · #34334d · #110d03
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#adff2f · #a3c9f1 · #008df1 · #9c003c · #460016 · #000618
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#B9FA6D · #C5F493 · #D0EEB3
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.
