Under warm 2700K interior light Sea 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 ≈ 1.3), 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.
#9edfb4 · #6fb98a · #2e8b57 · #0f6f3f · #004826 · #002410
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.
#4cada4 · #339d80 · #2e8b57 · #427433 · #4b5d10 · #4a4700
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.
#3ac9da · #68a0a7 · #2e8b57 · #1e6b40 · #004d29 · #002c32
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.
#bfeacd · #c77db7 · #2e8b57 · #485e4f · #19442b · #0d2516
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f9eef6 · #87968b · #2e8b57 · #625b60 · #1b2a20 · #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 · #a597a1 · #2c1c29 · #090107 · #2e8b57
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#ffebfa · #b67ba9 · #2e8b57 · #844077 · #410b39 · #000601
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffebfa · #9f83c1 · #2e8b57 · #923c54 · #32144d · #130003
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#eef1ff · #818dcc · #2e8b57 · #94402b · #4b0a00 · #01000e
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#45875E · #568365 · #637F6C
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.
