Pop art from bridge over the train line

I took this photo from one end of a concrete bridge, a relatively new addition to the local area. I was attracted to the little coloured rectangles of windows in the buildings in the distance - blue, purple and magenta - and I wondered what I could do with some colour enhancement. I put it through one of the pop art filters in my Olympus camera and what a happy surprise! It turned the grey of the concret bridge to bright yellow! And the sky behind to purple, so we have complementary colours which are naturally pleasing.

Thanks for hosting Ingeborg.
