Under warm 2700K interior light Night Mode shifts subtly: leans toward purple; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.5), so it is a lighting-stable choice.

Against white it measures 8.38:1 and against black 2.51:1, so white text is the stronger pairing. That pairing passes WCAG AA for body text. Avoid black 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.
#8eafdc · #6488ba · #3b6399 · #234e86 · #001f4b · #00051e
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.
#307a93 · #22658e · #234e86 · #2d3871 · #2e2558 · #29133f
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.
#b09cc2 · #9975b8 · #726282 · #234e86 · #103360 · #001a40
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.
#e8b871 · #798fad · #616e7f · #234e86 · #1d324e · #0b1727
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f8f1e7 · #a1abb7 · #6b6660 · #234e86 · #2e3743 · #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.
#f8f1e6 · #d3cabf · #aaa093 · #382d1c · #170b00 · #234e86
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#dbdcb7 · #92c5d4 · #f07240 · #7e5059 · #234e86 · #10082d
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#fef0db · #d79a7d · #6f6a0d · #234e86 · #5a2404 · #040300
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffeded · #da9498 · #4a7434 · #234e86 · #1f400a · #100001
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#2E4F7A · #384F6F · #404F63
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.
