Against white it measures 5.14:1 and against black 4.08:1, 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.
#b7c3e1 · #8f9cbd · #5f6d91 · #475374 · #28324e · #0c142b
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.
#6f98b1 · #6282a7 · #5f6d91 · #585783 · #52446a · #483351
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.
#bf9bc8 · #96849a · #5f6d91 · #435075 · #2a3656 · #27182b
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.
#d8c28c · #888e9d · #5f6d91 · #454f66 · #2a3246 · #121724
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f5f2ea · #848892 · #5f6d91 · #56544f · #1f222b · #030200
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.
#ecf2ff · #c1c9db · #5f6d91 · #182139 · #010115 · #e9be4d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#f8f1e1 · #98875e · #5f6d91 · #66521d · #2d2000 · #000008
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#f8f1e1 · #a58064 · #5f6d91 · #515a27 · #381900 · #010100
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffedea · #aa7b74 · #5f6d91 · #36603c · #072a0f · #050000
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#626D8A · #656E82 · #686E7B
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.
