Colour combinations 2 - inspiration from nature

In my last colour combinations post I mentioned blue and brown as a pairing new to me.  As a man of traditional inclination I've always stuck to conventional colours in my clothes, but now, in my search for taste in middle age, I am open to inspiration form any quarter, including nature.  How about green and purple?

These pictures of heather in full flower were take on a happy holiday in the Lake District last August - some ideas here for a tweedy tie, suit or shirt and jumper combination maybe?
