Dead leaves

The colour scheme for the next Twelve by Twelve challenge is "Rusty". I have no precise idea yet of what I want to do, but it makes me think of leaves changing their colours in autumn.
The first two pictures were taken in Japan last month. I know that it was in summer and the colours are not right for this challenge but I just like them.
The next photo is older. It was taken in my garden some years ago.
Now this leaf is really rusty, isn't it?
Terri, who chose this new colour scheme, also specified that it should be "rust with a blue-green patina".
