MonoMonday: Monochrome (but not B&W)

Here's my submission for today's MM challenge, hosted by V1K1 and AndrewNZ. They want a monochrome but using a single colour rather than black. I decided to have a "blue day" as I walked past a local shopping centre on the way to my regular Monday morning coffee meeting with some old retired colleagues. (My Editor calls it my Grumpy Old Men's Club! However after having had a good grump I didn't feel blue at all, Lol!)

This shopping centre was built several years ago to replace a hideous 1960s concrete construction - it's certainly a big improvement!
