Under warm 2700K interior light Swan Lake shifts subtly: drifts toward green; in north-facing or shaded light it shifts subtly: leans toward sky blue. Overall drift across common illuminants is small (max ΔE ≈ 2.2), so it is a lighting-stable choice.

Against white it measures 1.34:1 and against black 15.68:1, so black text is the stronger pairing. 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.
#dbf9f6 · #c5e5e2 · #8da9a6 · #6a8280 · #495e5c · #2a3c3a
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.

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.
#c5e5e2 · #a9c1d4 · #6eaba6 · #5685a9 · #356e6a · #334a5c
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.
#c5e5e2 · #aabfbd · #b47982 · #3c5f5c · #21403e · #0f2321
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#c5e5e2 · #c7bebf · #7d8988 · #554f50 · #172423 · #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.
#c5e5e2 · #91a19f · #324644 · #142827 · #000706 · #e64d72
The same quiet ground carrying one bright gold voice — the high-energy pairing a cool or muted anchor cannot reach through its own temperature.
#c5e5e2 · #91a19f · #324644 · #142827 · #000706 · #efbb4d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#c5e5e2 · #cebbbd · #a7787e · #743e48 · #39111a · #000202
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#c5e5e2 · #cebbbd · #a07992 · #744230 · #34132a · #0d0100
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#c5e5e2 · #c5bdcb · #917da2 · #6b491d · #321b00 · #020005
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

Its high lightness and low chroma make it a natural background or large-surface color. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
