Well, over here in the UK we have had plenty of grey skies, but I can’t imagine we want to see any more of those for Carmi's current Challenge, which this week is GREY.
A grey sky, on the other hand makes for grey reflections in the Lake in our Park.
Shadows on our fence. The wood has matured to a lovely silvery colour.
Grey rope on an old greyish table
And lastly, the mosaic patterns on a pedestrian square in Lisbon. It is, of course, perfectly flat, but looking at that wavy pattern made me feel a bit sea-sick!
None of these photos has been taken in Black and White mode. They are all truly GREY!
