Under warm 2700K interior light Aqua shifts noticeably: leans toward green, loses intensity; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 2.6), so it is a lighting-stable choice.

Against white it measures 1.41:1 and against black 14.92:1, 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 · #0ff0fe · #00b8c3 · #008e96 · #00666c · #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.
#0ff0fe · #25d6fd · #44bbf6 · #59a0e7 · #6786d3 · #6e6db9
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.
#0ff0fe · #94b7e3 · #00a9b4 · #3078cb · #00686e · #1f4169
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.
#0ff0fe · #91babd · #d4605f · #005b61 · #003b3f · #001d20
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#0ff0fe · #c4b3b1 · #6c8688 · #564a49 · #062426 · #060101
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.
#fceeed · #d6c5c4 · #ab9997 · #35201f · #110202 · #0ff0fe
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#0ff0fe · #d2adab · #bc615f · #8c1b25 · #430007 · #000203
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffedd8 · #0ff0fe · #d9b4a0 · #cb6095 · #483a54 · #041119
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#0ff0fe · #c5afc8 · #a167a9 · #644700 · #2b1c00 · #050008
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#67EBF5 · #8EE5EC · #ACDFE3
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.
