What is the colour of rusty iron filings?

Explanation:
Rust forms when iron reacts with oxygen in the presence of water, producing iron oxide. That corrosion product has a reddish-brown colour, so rusty iron filings look brown. The other colours don’t fit rust: blue or green would come from different metals or other types of corrosion, and white isn’t the typical colour of rust. So brown is the colour you’d see.
