Lovely colour even on a grey day!

I have been noticing this tree changing colour as I frequently pass it. The leaves are falling quickly now!
Very chilly today when I went for a bike ride but still lots of people out walking and a few running at about 10.30am ...about 80 on the towpath between Kingston Bridge and Hampton Court Palace, this included three groups of teenagers with rucksacks and maps dangling from their necks, possibly doing a D of E walk .
