Building a palette around Rust
The pairings above give you three classic starting points. The complementary color sits opposite on the wheel and works well as an accent that draws the eye. The analogous colors sit right beside Rust for calmer, harmonious combinations. The triadic pair spaces three hues evenly for a balanced, energetic palette. Open any swatch to explore it as its own color, or open the palette generator with Rust locked and let it fill in the rest.
