Against white it measures 6.73:1 and against black 3.12:1, 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.
#ff9589 · #e85c52 · #bb0011 · #8e0009 · #550002 · #240000
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.
#c46c00 · #bf4900 · #bb0011 · #9a0039 · #7a0046 · #5b0049
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.
#e4b565 · #cd9100 · #a07830 · #bb0011 · #8a0009 · #5c0003
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.
#00ddf2 · #a4756f · #bb0011 · #752621 · #4f0908 · #260000
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#ddf8fc · #ceaca8 · #6e8183 · #bb0011 · #62403b · #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 · #bccdd0 · #8ea1a4 · #0f2a2d · #000709 · #bb0011
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#cdd6b2 · #cc9dbe · #2ea695 · #bb0011 · #435940 · #190c03
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#d3dcb7 · #85b4dc · #64a29e · #bb0011 · #455644 · #190b03
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#d8fedb · #64d176 · #476ff3 · #bb0011 · #213ba5 · #000200
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#AB312B · #9A443D · #88524C
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.
