Against white it measures 8.21:1 and against black 2.56:1, 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.
#86a3ce · #5d7dac · #2d4f83 · #173665 · #00163e · #00001b
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.
#3c7a93 · #2f658c · #2d4f83 · #323a6d · #312755 · #2b153d
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.
#b29ec0 · #9b78b4 · #746480 · #2d4f83 · #19345e · #031b3f
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.
#e6bd7c · #7d90ac · #646f7f · #2d4f83 · #22334d · #0e1827
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f7f1e8 · #a3abb7 · #6c6862 · #2d4f83 · #303844 · #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 · #d3cbbf · #aaa194 · #392e1d · #170d00 · #2d4f83
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#dcdeb9 · #94c7d8 · #d97b50 · #86555d · #2d4f83 · #10072a
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#c3dfc1 · #b8bb73 · #a28777 · #566954 · #2d4f83 · #041117
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffeded · #d79798 · #4b753e · #2d4f83 · #204115 · #0f0001
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#355078 · #3D506E · #445063
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.
