Under warm 2700K interior light Dark Sea 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 ≈ 1.7), 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.
#d8fed7 · #acd6ac · #8fbc8f · #618862 · #416341 · #224023
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.
#a9e3d3 · #99d0b2 · #8fbc8f · #8ea574 · #898e5e · #82784d
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.
#8fbc8f · #739798 · #597d59 · #006264 · #244325 · #002829
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.
#c8d6c8 · #8fbc8f · #a57ca8 · #5d735c · #405340 · #283428
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f6eff6 · #8fbc8f · #8d958d · #5b575b · #1e271e · #020102
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.
#f6eff7 · #cec6ce · #a298a2 · #291e2a · #070108 · #8fbc8f
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#faedfb · #8fbc8f · #a785a8 · #6e4871 · #341736 · #000200
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#faedfb · #8fbc8f · #958bb6 · #7b445b · #271c41 · #050001
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ecf2ff · #8fbc8f · #7f92ba · #7f4541 · #3f1413 · #000008
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#96B996 · #9DB69D · #A3B3A3
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.
