Under warm 2700K interior light Fisher King 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 4:1 and against black 5.24:1, so black 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.
#b9d9ff · #87b2e4 · #5182b9 · #396799 · #1a446f · #002348
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.
#68afc5 · #5899c0 · #5182b9 · #576ba4 · #57558b · #534170
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.
#cbacf1 · #a496b7 · #5182b9 · #3d6491 · #244870 · #332543
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.
#d6e9ff · #e5b373 · #5182b9 · #536170 · #2b435e · #192636
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f8f1e8 · #919ba6 · #5182b9 · #69645e · #212a35 · #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.
#f9f0e7 · #d4cbbf · #aba194 · #3b2e1f · #190d00 · #5182b9
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d4dbb5 · #e39676 · #5182b9 · #69648d · #4d2f37 · #0e0931
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffefdc · #c58a73 · #5182b9 · #706610 · #4a1700 · #050300
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffedee · #c6868c · #5182b9 · #4e7131 · #193100 · #0c0001
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#5C82AD · #6681A1 · #708195
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.
