Under warm 2700K interior light Sky Blue shifts subtly: leans toward blue-green, loses intensity; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 2.3), so it is a lighting-stable choice.

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.
#e1f6ff · #87ceeb · #6badc7 · #4a869d · #2b6175 · #093e4f
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.
#abebe9 · #96ddea · #87ceeb · #84b6dc · #829fc8 · #7e88b2
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.
#87ceeb · #9ca1bd · #548ea5 · #5c6396 · #1b5367 · #2c2f48
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.
#d6eaf3 · #87ceeb · #cb9075 · #628593 · #466471 · #31444d
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#87ceeb · #ada4a0 · #6a767b · #4a4442 · #121e23 · #050201
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.
#faefea · #d4c7c2 · #a99b95 · #34241c · #110401 · #87ceeb
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#dee0bb · #87ceeb · #e96440 · #586dab · #50323f · #031128
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#87ceeb · #b4a299 · #976467 · #5f3e01 · #360a11 · #0f0500
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#87ceeb · #b2a0a9 · #91657c · #4c4803 · #1f1d00 · #040002
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.
