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

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.
#d3ffdc · #00ff7f · #00c25f · #009648 · #006c32 · #00451d
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.
#a5ffdb · #00ff7f · #7de02e · #a4be00 · #aea000 · #ac8400
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.
#00ff7f · #3dcbd7 · #00b558 · #008992 · #006f33 · #004b50
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.
#00ff7f · #ea56de · #517c5b · #00622d · #00401a · #002109
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#00ff7f · #c6b2c3 · #6d8a73 · #564954 · #062711 · #030003
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.
#f8eef7 · #d0c5ce · #a497a2 · #2c1c2a · #090108 · #00ff7f
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#00ff7f · #d4a9ce · #bd4db4 · #83007c · #3a0037 · #000200
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffe9e4 · #00ff7f · #e6b1bb · #b879d3 · #354062 · #04110f
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#00ff7f · #a8b7e7 · #5a74f0 · #930e00 · #430000 · #010011
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.
