What a glorious little parade of primary colours on a humble parking meter on a quiet Parisian street. Shame they didn't have the spunk to paint the 'Langue' button rainbow hued, but that's the linguist artist in me speaking!
And purple and orange indeed. Surely they could have squeezed them in somewhere. You'd have to be inside an urban street furniture architect's head to understand the finer points of the equation I suppose.
