#848789rgb(132, 135, 137)hsl(204, 2%, 53%)oklch(0.622 0.005 236.5)Aluminium 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 curated palettes it appears in and any public brand that adopts it.
Charcoal, Champagne and Copper 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 that reads cleanly against Aluminium without the hard edge of pure #000.
6 real palettes, including Midnight Luxe and Forest Floor put Champagne beside Aluminium, as that palette's text colour.
Designers have shipped Copper with Aluminium: 5 real palettes, including Atelier and Clay & Linen, as the accent.
Crimson is paired with Aluminium in 5 real palettes, including Retro Pop and Diner, as the lead colour.
Designers have shipped Denim with Aluminium: 9 real palettes, including Dusk and Campus, as the lead colour.
Goldenrod shows up next to Aluminium in 4 real palettes, including Noir Beauty and Ledger Dark, as the lead colour.
Hunter Green is paired with Aluminium in 4 real palettes, including Bookshop and Darkroom, as the accent.
6 real palettes, including Plaid's brand system and Open House put Midnight Blue beside Aluminium, 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 Aluminium as the background.

Black on bone with a whisper of gold: the runway default that lets garments carry the color.
Black, gold and one deep red — the prestige cosmetics counter: all restraint and a single lipstick.
A pure greyscale with a single electric blue — the portfolio palette that makes work look considered.
Ink-black and ribbon-red on manila — the correspondence palette; all the vintage comes from the paper colour.
Greys on near-black — the monochrome dark mode; keep everything a tint of white and the layout does the talking.
Aluminium reads as neutral, minimal. The font library is tagged with the same vocabulary:

Every direction it proposes comes with a /colors/d/… link: open it, lock what you like, paste the link back, and the agent edits rather than re-rolls.
