Against white it measures 5.82:1 and against black 3.61:1, 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.
#ffa6ab · #f66375 · #c90b42 · #9d0030 · #64001b · #300008
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.
#dd6b24 · #d7452e · #c90b42 · #a80058 · #860063 · #640065
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.
#ea9200 · #b47d3e · #c90b42 · #99002f · #6b001e · #2e1800
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.
#00dfe1 · #b07e80 · #c90b42 · #812d38 · #5b111f · #31030b
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#dcf8f8 · #9f7d7f · #c90b42 · #455858 · #36171a · #000202
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.
#e6f5f5 · #bccdcd · #8ca0a0 · #0b2727 · #000505 · #c90b42
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#c4ffff · #009b9c · #c90b42 · #006061 · #002829 · #180002
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#c4ffff · #009f74 · #c90b42 · #005d77 · #002a1c · #00050b
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#e0fcd2 · #559d23 · #c90b42 · #0051a4 · #00204b · #000200
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#B8374C · #A74C55 · #945A5E
Its chroma is high enough to carry accents, calls to action, and focal moments; large fields of it will dominate a composition. In palettes it pairs most predictably with its tonal ramp and analogous neighbors; reserve the complementary hue for small, deliberate contrast.
