Under warm 2700K interior light Castaway shifts subtly: leans toward green, loses intensity; in north-facing or shaded light it shifts subtly: leans toward sky blue. Overall drift across common illuminants is small (max ΔE ≈ 2), so it is a lighting-stable choice.

Against white it measures 2.23:1 and against black 9.43:1, 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.
#cffcff · #91d7dd · #6dbac0 · #44898e · #236469 · #004145
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.
#abdfcc · #8bcdc5 · #6dbac0 · #63a4b6 · #5e8ea8 · #5a7897
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.
#6dbac0 · #7d8ea4 · #3b7a7f · #34557c · #004145 · #112033
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.
#bed3d5 · #6dbac0 · #b47774 · #2d5255 · #133436 · #041819
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f9efee · #6dbac0 · #859394 · #5b5554 · #192627 · #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.
#faefee · #d3c6c5 · #a99a99 · #322120 · #0f0203 · #6dbac0
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#ffedec · #6dbac0 · #b2817f · #7c4443 · #3d1414 · #000203
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffedec · #6dbac0 · #ae8093 · #78492c · #3a1427 · #110300
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#faedfb · #6dbac0 · #a283a6 · #6c521e · #302000 · #030004
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#7DB7BC · #8BB4B7 · #98B1B3
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.
