Against white it measures 12.5:1 and against black 1.68:1, 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.
#a5a4a7 · #807e82 · #5c5a5e · #353337 · #1c1b1e · #040304
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.
#4b5174 · #453d64 · #353337 · #351838 · #290820 · #1b000b
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.
#bd9ca5 · #927ea4 · #8e5868 · #60464d · #353337 · #241232
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.
#b6ce9a · #766a81 · #544e5b · #353337 · #1f1428 · #06020a
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f0f3ec · #b9b4be · #7e807b · #4e4953 · #353337 · #1c1f19
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.
#f2f1f3 · #cfced0 · #a8a7aa · #575659 · #353337 · #a9d66d
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#edf5e5 · #acbf96 · #728857 · #41522b · #353337 · #23192c
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#edf5e5 · #c1b88c · #578d6e · #554c20 · #353337 · #0d2317
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#fcefe2 · #d1b08e · #438e88 · #165752 · #353337 · #2a1a09
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

As a deep tone it works for grounding elements — text, outlines, and shadowed surfaces — rather than open fields.
