When I was young I went through two 'favourite colours' phases, almost like a premonition of what was to come.
The first combination I fell in love with was green and purple, two secondary colours which seemed to me to go splendidly together, despite the rather unorthodox pairing.
The second was blue and orange, and I've never fallen out of love with this particular alliance.
All that remains is to see how often nature, or urban architecture, throws up one or another of these curious couplings to titillate and regale my retinas.
The grim grey of the grimy street just makes the colours pop all the more. Thank goodness for colour!
And why not...
