Under warm 2700K interior light Sail On shifts subtly: leans toward purple, loses intensity; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 1.9), so it is a lighting-stable choice.

Against white it measures 4.77:1 and against black 4.4:1, 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.
#a6ccfa · #7aa5d8 · #4575ad · #2e5a8d · #0e3864 · #001939
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.
#5aa2b9 · #4a8cb4 · #4575ad · #4c5e97 · #4d497f · #483664
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.
#be9ee3 · #9889aa · #4575ad · #315885 · #183c65 · #291b38
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.
#e7b472 · #8795a6 · #4575ad · #3d5572 · #233850 · #0f1c2c
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f8f1e8 · #858e9a · #4575ad · #5d5852 · #1c2530 · #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.
#f8f0e7 · #d4cbbf · #aba194 · #3b2e1e · #190d00 · #4575ad
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d0debb · #d2bb64 · #8c7ba8 · #4575ad · #765549 · #041014
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffefdc · #b87d65 · #4575ad · #635b00 · #421300 · #050300
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffedee · #b9787f · #4575ad · #416524 · #142c00 · #0d0001
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#5075A1 · #5A7595 · #647488
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.
