Under warm 2700K interior light Zenith shifts subtly: leans toward blue, loses intensity; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.8), so it is a lighting-stable choice.

Against white it measures 4.6:1 and against black 4.57:1, so white text is the stronger pairing. 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.
#aad0ef · #7ea9cb · #497a9f · #315f81 · #123d5a · #001d32
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.
#6aa3ae · #568fa7 · #497a9f · #49648d · #475078 · #423c61
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.
#b4a8df · #938ea8 · #497a9f · #355c7a · #1c415b · #252037
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.
#c5dff3 · #d7a87f · #497a9f · #4a5762 · #233b4d · #111f29
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f7f0ea · #879198 · #497a9f · #5f5a56 · #1d262e · #020100
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.
#f8f0e9 · #d3c9c1 · #a99e95 · #36291e · #130801 · #497a9f
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#cedfbc · #cbbf66 · #497a9f · #525c87 · #402e26 · #041013
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#feefe2 · #b28277 · #497a9f · #6a5920 · #40170f · #0a0500
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffecf0 · #b1808c · #497a9f · #53622d · #202a00 · #050001
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#547996 · #5E788D · #667784
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.
