#222233rgb(34, 34, 51)hsl(240, 20%, 17%)oklch(0.26 0.032 284)Black Velvet on this page is the real value, not a screenshot: exact hex, RGB, HSL and OKLCH, ten tints and ten shades, classic harmonies, and WCAG contrast with fixes — plus the 4 public brands that use it and the palettes it appears in.
Charcoal, Dark Olive Green and Sea Green lead the list. Each partner is a real named colour with the reason it works — a wheel relationship, a neutral that carries it, or a pairing lifted from a palette or brand system that actually shipped — and every pair opens in the palette tool.
Charcoal is the text near-black for Black Velvet: softer than #000 and cool enough to feel like part of the same palette.
Dark Olive Green sits directly opposite Black Velvet on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Sea Green is a split-complement of Black Velvet: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Sienna is a split-complement of Black Velvet: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Slate Blue is Black Velvet's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.
Steel Blue is Black Velvet's neighbour on the wheel, so the two read as one family — use it for hover states, gradients and secondary surfaces.
Teal completes a triad with Black Velvet — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.
Amber is paired with Black Velvet in 18 real palettes, including Beach Hut and Wikipedia's brand system, as the supporting colour.

Fixes keep hue and saturation and move lightness only, so the suggestion stays on-brand. Ratios are symmetric: the same numbers apply with Black Velvet as the background.
Slate blue with a copper accent — calm, professional, slightly editorial; suits consultancies and journals.
Pastels pushed to the saturated end — pink, sky and lemon — for brands that want soft AND loud.
Sea-green and slate with a coral — a literal tide pool: two cool tones, one warm creature.
Black Velvet reads as cool, muted, dark. The font library is tagged with the same vocabulary:
