Rust is primarily various shades of reddish-brown.
While the reference provides a method for creating the appearance of rust using red paint, it doesn't explain what colors make up actual rust. Rust, scientifically known as iron oxide, typically appears in a range of reddish-brown hues. The specific shade can vary depending on factors like:
- The type of metal rusting: Iron and its alloys (like steel) produce the familiar reddish-brown rust.
- The presence of other elements: Other elements present during the oxidation process can influence the color.
- The degree of oxidation: Lighter shades may appear early in the rusting process, while darker shades develop as oxidation progresses.
- Moisture levels: Different moisture levels can influence rust formation and color.
In essence, rust is a natural chemical process (oxidation) that results in a range of reddish-brown colors. The provided reference describes an artistic technique to mimic the visual appearance of rust but doesn't address the actual color composition of rust itself.
