How Onyx behaves under real light

Under warm 2700K interior light Onyx is virtually unchanged; in north-facing or shaded light it is virtually unchanged. Overall drift across common illuminants is small (max ΔE ≈ 0.9), so it is a lighting-stable choice.

Contrast & accessibility

Against white it measures 9.57:1 and against black 2.2:1, so white text is the stronger pairing. That pairing passes WCAG AA for body text. Avoid black text on this color entirely.

Palettes built from Onyx

Tonal

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.

#dededd · #b7b6b5 · #929190 · #6c6b6a · #464544 · #292928

Analogous

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.

#6e673f · #675227 · #464544 · #512a10 · #40190f · #2e0b0d

Shifted

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.

#b7bfa2 · #b59574 · #788450 · #5e644c · #464544 · #402400

Contrast

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.

#719bc3 · #6c6156 · #464544 · #372511 · #1a0c00 · #070200

Quiet Support

The anchor as the only color in the room. True neutrals or complement-warmed near-neutrals let it stay dominant.

#ecf3f9 · #aba39b · #5a5e62 · #464544 · #342d25 · #000102

Bright Accent

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.

#f2f2f1 · #b0b0af · #91908f · #676665 · #464544 · #f3a649

Complementary

The opposite hue on the perceptual wheel, tempered to field strength — warm/cool tension without vibration.

#e8f3ff · #87a9c9 · #396186 · #464544 · #0f304c · #130600

Split-complementary

The complement's two neighbours instead of the complement itself — strong contrast with a lower clash risk.

#e8f3ff · #79aebe · #545a88 · #464544 · #003440 · #010007

Triadic

Three hues spaced evenly around the wheel; the anchor leads and the other two are held at supporting strength.

#e2f7f4 · #78b1ab · #69527f · #464544 · #372447 · #000202

Tetradic

Two complementary pairs offset by 90° — the richest chord, kept usable by a strict lightness hierarchy.

Using Onyx

Its moderate chroma lets it work in mid-size areas — upholstery, secondary UI surfaces, editorial blocks — without overwhelming neighbors.
