Against white it measures 6.12:1 and against black 3.43:1, 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.
#ff9d9b · #e26d6e · #b52f3a · #921024 · #5d000f · #2a0003
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.
#c87233 · #c15230 · #b52f3a · #99204b · #7a1752 · #5c1053
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.
#e8ba7e · #dc9200 · #a47d48 · #b52f3a · #8a1c27 · #640011
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 · #a57c7b · #b52f3a · #743233 · #4f1719 · #280507
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#e0f7f8 · #967a79 · #b52f3a · #435253 · #311817 · #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 · #b52f3a
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#dbd6b0 · #d2a2c1 · #2fa8c9 · #b52f3a · #42577b · #030e1f
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#bddabe · #78c59c · #6ea0b2 · #b52f3a · #435174 · #1f0513
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#e0fbdb · #4f9645 · #b52f3a · #0e46a9 · #001955 · #000200
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#A74245 · #984F4F · #885A58
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.
