Against white it measures 18.24:1 and against black 1.15:1, 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.
#acacad · #868688 · #626264 · #404042 · #151517 · #060608
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.
#285969 · #1d465f · #183353 · #162045 · #151517 · #0d021c
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.
#af94a6 · #7c7aa2 · #7e5171 · #444168 · #392633 · #151517
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.
#cac88f · #69697a · #4a4960 · #2e2e3b · #151517 · #02010d
The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.
#f2f2ea · #babac5 · #888782 · #555561 · #2b2b24 · #151517
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.
#f2f2f3 · #cbcbcc · #a1a1a2 · #2e2e2f · #151517 · #d1c94e
The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.
#f3f3e2 · #c0be91 · #8d8a54 · #5b592d · #29283c · #151517
The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.
#f3f3e2 · #d2b690 · #739264 · #6b522c · #222f1c · #151517
Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.
#ffeee6 · #ddb09b · #58967d · #30624e · #3a251a · #151517
Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

#121213 · #0e0e0f · #0b0b0c · #070708 · #040404
As a deep tone it works for grounding elements — text, outlines, and shadowed surfaces — rather than open fields.
