Under warm 2700K interior light Nautical 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 8.78:1 and against black 2.39:1, 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.
#859dc8 · #5d77a6 · #2e4a7d · #18315f · #011239 · #000015
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.
#3c758e · #306087 · #2e4a7d · #313567 · #2f234f · #281237
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.
#ae9ab9 · #9873ab · #715f7a · #2e4a7d · #1a3058 · #05163a
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.
#e3be7e · #7b8ba7 · #616a7a · #2e4a7d · #202e48 · #0c1423
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f6f1e8 · #a2a9b4 · #67645e · #2e4a7d · #2d343f · #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.
#f7f1e7 · #d1cbbf · #a8a093 · #362c1c · #140b00 · #2e4a7d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#fbf0dd · #c0a472 · #7f5e1a · #2e4a7d · #452f00 · #00000a
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#fbf0dd · #ce9b7e · #666923 · #2e4a7d · #522605 · #020200
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffedec · #d39694 · #44713e · #2e4a7d · #193d15 · #060000
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#354B73 · #3B4B68 · #414C5E
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.
