Blue and white are a bit of a chameleon pair. Think of sky blue and white and it's all beach towels and boat houses and sunny Greek islands. But dial up the darkness on the blue a little and suddenly it's all oh la la - breton tops, berets and strolling the French riviera. And go darker still and it's all things nautical - yachts and sailors, brass buttons and the Royal Navy. Kind of impressive that one pairing of colours can evoke so many memories and cliches. I can't think of another that does, can you?
ps. That top diptych is a sunny day in Tokyo paired with a snowy day in Seoul!
