Under warm 2700K interior light Copacabana shifts subtly: leans toward blue-green, loses intensity; in north-facing or shaded light it shifts subtly: leans toward blue. Overall drift across common illuminants is small (max ΔE ≈ 1.6), so it is a lighting-stable choice.

Against white it measures 5.95:1 and against black 3.53:1, so white 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.
#84c0db · #549ab8 · #006c8d · #00506a · #002e3e · #000f18
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.
#479394 · #248090 · #006c8d · #1c567f · #26416d · #282d57
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.
#b5b9df · #9197d8 · #797c9c · #006c8d · #004e67 · #003244
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.
#a6cddf · #d5906d · #006c8d · #344750 · #012d3c · #00111a
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#faefea · #a9b8bf · #827a77 · #006c8d · #3c4c53 · #030100
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.
#fbefe9 · #d6c8c1 · #ad9d95 · #3b281f · #180701 · #006c8d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#ffeee5 · #dfa78a · #ab6947 · #006c8d · #6d3a1e · #000409
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffeee5 · #e2a2a3 · #9c7432 · #006c8d · #6f3538 · #100600
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffecf5 · #dba1be · #828036 · #006c8d · #4e4c0a · #050002
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.
