Under warm 2700K interior light Light Sea Green shifts subtly: leans toward green; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.9), 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.
#c6fffa · #74ded6 · #20b2aa · #009089 · #006762 · #00423e
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.
#7ccfea · #51c1cd · #20b2aa · #319e83 · #408960 · #497342
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.
#9bc0dd · #20b2aa · #1a9089 · #01679b · #00514d · #052f48
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.
#b2f0ea · #a6c6c2 · #20b2aa · #b35b6c · #306662 · #224442
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#fceeef · #20b2aa · #728583 · #544b4c · #0e2422 · #040101
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.
#fceeef · #d5c4c7 · #aa979a · #321d21 · #0e0103 · #20b2aa
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d1dcb8 · #20b2aa · #6a966a · #ca253e · #432c40 · #1c0515
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffedef · #20b2aa · #a56b93 · #7f3216 · #3a042e · #1f0200
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#f7eeff · #20b2aa · #9171aa · #6d4200 · #301900 · #030009
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#4FAEA7 · #6AA9A4 · #7FA4A1
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.
