Against white it measures 8.83:1 and against black 2.38:1, 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.
#b191bd · #8d6a9a · #623b70 · #472454 · #260530 · #06000d
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.
#6a6999 · #665287 · #623b70 · #582951 · #4a1a35 · #3b0b1b
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.
#c3989e · #b86d7b · #825e64 · #623b70 · #43244e · #280c32
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.
#a7d395 · #9984a0 · #736778 · #623b70 · #3b2842 · #1c1120
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#eef4eb · #aea6b2 · #646862 · #623b70 · #3b323e · #000100
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.
#edf4ea · #c4ccc0 · #96a093 · #1d2818 · #010700 · #623b70
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d7dcb6 · #daaecf · #67a87a · #58664d · #623b70 · #0d0a28
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#c8f9f9 · #ccdc89 · #76978d · #536553 · #623b70 · #1e0512
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#fdf0dd · #c5a372 · #007577 · #623b70 · #003e40 · #0f0500
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#5E4069 · #5A4462 · #55485A
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.
