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.
#f18b8a · #cf5d60 · #ac2c37 · #990022 · #470009 · #180001
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.
#ad570c · #a63510 · #990022 · #7a0035 · #5c003b · #3f0039
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.
#cd9f62 · #ba7a00 · #8b642d · #990022 · #6b0014 · #400007
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.
#00dee9 · #bf7a79 · #8b6362 · #990022 · #5a191d · #2f0a0c
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#e0f7f8 · #c0a3a2 · #5d6d6e · #990022 · #4c302f · #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.
#e6f5f6 · #bccdce · #8da1a2 · #0c282a · #000607 · #990022
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#dbdab5 · #d8b88e · #2485b0 · #59648d · #990022 · #020a2a
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#c5e0c2 · #80d2a8 · #528593 · #55658a · #990022 · #200514
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#dffbdb · #77c16b · #2963cb · #990022 · #003083 · #000200
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#8C262E · #7E3638 · #6F4241
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.
