Under warm 2700K interior light Muted Blue shifts subtly: 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 5.19:1 and against black 4.05:1, 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.
#9dc7ed · #71a0ca · #3b719f · #235680 · #013458 · #00152b
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.
#589bab · #4487a6 · #3b719f · #415b8c · #424675 · #3e335d
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.
#b09cdb · #8d84a3 · #3b719f · #285479 · #0e395a · #211732
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.
#dfab76 · #808f9d · #3b719f · #365168 · #1c3347 · #091824
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f8f0e9 · #7e8892 · #3b719f · #57524d · #19232c · #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 · #d4cac0 · #aca095 · #3b2d1f · #190c01 · #3b719f
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#ffefdf · #a67e56 · #3b719f · #75470b · #341b00 · #000615
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#ffefdf · #af7767 · #3b719f · #625200 · #400f03 · #080400
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffecef · #ae7480 · #3b719f · #465c1d · #1a2700 · #070001
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#487195 · #53708A · #5D6F7F
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.
