Against white it measures 5.85:1 and against black 3.59:1, 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.
#ffa79f · #f9625e · #cc0021 · #9e0017 · #64000a · #300002
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.
#d67200 · #d34b00 · #cc0021 · #aa0045 · #890053 · #680058
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.
#de9900 · #ae8035 · #cc0021 · #9a0016 · #6b000b · #2b1a00
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.
#00ddef · #b17e79 · #cc0021 · #822d2b · #5c1012 · #310304
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#dbf8fb · #a07d7a · #cc0021 · #445759 · #371715 · #000304
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.
#e6f5f7 · #bccdcf · #8ea1a4 · #0f2a2d · #000709 · #cc0021
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d1dab5 · #30b09a · #9e7296 · #cc0021 · #4b5f46 · #180b03
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#d3fbff · #009d83 · #cc0021 · #005a7f · #002920 · #00050d
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#d8fed7 · #2ea03c · #cc0021 · #153ec7 · #020074 · #000200
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#BB3636 · #A94B47 · #955A55
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.
