Colors that go with Rust
Sea Green, Steel Blue and Teal 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.
Sea Green #2e8b57
triadicshippedSea Green completes a triad with Rust — three hues spaced evenly round the wheel, the classic way to get energy into a palette without a clash.
Steel Blue #4682b4
split-complementshippedSteel Blue is a split-complement of Rust: nearly opposite, so it still pops against it, without the vibrating edge of a true complement.
Teal #008080
complementaryshippedTeal sits directly opposite Rust on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
Amber #ffbf00
shippedAmber is paired with Rust in 6 real palettes, including Trailhead and Ember, as the accent.
Blue #0000ff
shipped4 real palettes, including Tim Hortons's brand system and Doordash's brand system put Blue beside Rust, as the accent.
Champagne #f7e7ce
shipped6 real palettes, including Woodsmoke and BrandSweets's brand system put Champagne beside Rust, as the text colour against it.
Charcoal #36454f
neutralshippedCharcoal is the body-text near-black for Rust: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
Dark Olive Green #556b2f
shippedDark Olive Green shows up next to Rust in 6 real palettes, including Magazine Ochre and BrandSweets'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 Rust as the background.
