Against white it measures 8.93:1 and against black 2.35:1, 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.
#e08375 · #bd574a · #911911 · #6d0000 · #370000 · #0d0000
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.
#a25d0e · #9c3e00 · #911911 · #780228 · #5b0030 · #3f002f
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.
#c2a166 · #af7e00 · #826632 · #911911 · #680100 · #3e0000
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.
#00dcf5 · #b97c72 · #87645e · #911911 · #551d16 · #2c0b08
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#e2f6fa · #bda39f · #5d6b6d · #911911 · #48302c · #000305
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 · #8ea2a5 · #102b2f · #00080b · #911911
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#d7f9ff · #14bfd5 · #007583 · #911911 · #003f47 · #080000
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#dbdfb9 · #8ec8e3 · #5b8878 · #596b55 · #911911 · #1b0c03
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ddfbe1 · #6dc07e · #455ec0 · #911911 · #1d2c7a · #000200
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#852D23 · #783931 · #6A433C
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.
