Red door in monchrome frame

I don't have a fancy camera that does clever things with mono images by highlighting just one aspect in colour, as in this shot by walkingMarj. However, there are ways of getting this effect without any technical jiggery-pokery if you choose your subjects well. This is the side door to Mansfield Traquair, a former Catholic Apostolic Church not far from my flat.

Exercise today: morning loops in 28'54", sit-ups and weights, walk to work (1 hour), walk a bit further to work for a meeting (30 minutes).
