Rust

One of the tin tubs I used for alpines got so full of weeds I dumped everything out and left it empty ready for this year. Lots of rain has meant it filled up and rusted. I keep passing it on the way to the clothes line and seeing the colour of the rust. Today I decided to photograph it. The main photo is it from one angle, the two in extras are from slightly different angles and for some reason almost totally different colours
