Under warm 2700K interior light Lagoon shifts subtly: leans toward green; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.8), so it is a lighting-stable choice.

Against white it measures 3.28:1 and against black 6.41:1, so black text is the stronger pairing. 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.
#b7f1ea · #87cac3 · #4b9b93 · #327e77 · #0b5953 · #003531
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.
#83bacb · #65abb1 · #4b9b93 · #488873 · #477457 · #45603e
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.
#93aec1 · #4b9b93 · #397b74 · #1f5779 · #00413c · #072131
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.
#b1dad4 · #9db2af · #4b9b93 · #925763 · #325350 · #1f3432
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f9eff0 · #9caaa8 · #4b9b93 · #766f70 · #243230 · #020101
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.
#faeef0 · #d2c5c7 · #a7979a · #2e1d20 · #0a0102 · #4b9b93
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#ffecef · #cb96a0 · #4b9b93 · #985d69 · #4a1e29 · #000201
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffecef · #c198b6 · #4b9b93 · #99604f · #43203b · #050000
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#f6eeff · #b19dc7 · #4b9b93 · #90673b · #452700 · #020006
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#5D9891 · #6B9590 · #78918E
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.
