Against white it measures 11.75:1 and against black 1.79:1, 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.
#9ea0a3 · #797b7e · #55575b · #36383c · #16181b · #020203
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.
#345e73 · #294a6a · #36383c · #23244a · #1e1334 · #16041f
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.
#b6a3bd · #7a8cb1 · #80618c · #5b4c61 · #36383c · #101d3d
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.
#dbc18c · #6a758b · #4f5562 · #36383c · #131c30 · #03050f
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f5f1ea · #b4b9c2 · #84827d · #4b505a · #36383c · #24211b
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.
#f1f2f4 · #cfd0d2 · #a9abad · #5b5c5f · #36383c · #eebc4d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#f9f1e1 · #cbb68d · #977f4c · #604d24 · #36383c · #192134
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#f9f1e1 · #d8af95 · #818852 · #6b462d · #36383c · #21240e
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffedeb · #ddaaa6 · #668e66 · #395939 · #36383c · #321a19
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#2d2f32 · #242528 · #1b1c1e · #121314 · #09090a
As a deep tone it works for grounding elements — text, outlines, and shadowed surfaces — rather than open fields.
