With some Lifecolor Rust Wizard paints to hand, I washed my hut's walls with various shades of rust. Starting with the Deep Rust, I ended up with the bright orange and yellow colours in patches. Using these surprised me as I'm not a fan of bright colours but they really work for fresh rust bursting from the metal.
I'll set this on the layout and see how it looks.
