Gray, but not Grey

On the way back from taking Andy to the orthodontist, I saw bright colours on the side of these buildings. 

Turned out to be reflections from their colourful neighbour, the John Gray Centre. 

The lad was unimpressed by my interest: "Dad, you've taken loads of pictures of that before" (I haven't) and "People think you're taking photos of them" (pretty sure they didn't). 

Still, it seemed to distract him from the memory of wires being stretched and snipped in his mouth.
