#424f03rgb(66, 79, 3)hsl(70, 93%, 16%)oklch(0.402 0.094 120.1)Saddle Brown, Sage Green and Blue Violet 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.
Designers have shipped Saddle Brown with #424f03: 4 real palettes, including Bookshop and Domino's's brand system, as the lead colour.
Designers have shipped Sage Green with #424f03: 6 real palettes, including Pine & Birch and Stone, as the supporting colour.
Blue Violet sits directly opposite #424f03 on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Royal Blue is a split-complement of #424f03: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
3 real palettes, including Warp's brand system and Instacart's brand system put Blue beside #424f03, as the supporting colour.
3 real palettes, including Sweetgreen's brand system and Darkroom put Champagne beside #424f03, as the supporting colour.
Charcoal is the body-text near-black for #424f03: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
Designers have shipped Copper with #424f03: 3 real palettes, including Desert Road and Clay & Linen, as the lead colour.
