Under warm 2700K interior light Dark Cyan shifts subtly: leans toward green; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.7), so it is a lighting-stable choice.

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.
#95e0df · #62b9b9 · #008b8b · #006d6d · #004747 · #002424
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.
#67a7c2 · #3f99a9 · #008b8b · #0f7969 · #1f6549 · #28522d
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.
#81bcf2 · #7f9bb4 · #008b8b · #006b6b · #004c4c · #0f2a41
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.
#c7e8e7 · #94c8c7 · #86a0a0 · #008b8b · #884048 · #164444
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#fbeeef · #879898 · #008b8b · #655d5d · #192b2b · #030101
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.
#fceeee · #d6c5c6 · #ab9899 · #351f21 · #110103 · #008b8b
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#ffeded · #c08085 · #008b8b · #8e464d · #48101a · #000202
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffeded · #b7819f · #008b8b · #8c4b2d · #421231 · #1a0300
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#f9edff · #a686b6 · #008b8b · #80560b · #382200 · #030006
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#378887 · #4F8483 · #618080
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.
