Ok, it's aqua but 'Thin Aqua Line' doesn't really work...
Left work just as the promised severe weather arrived and the heaven's opened which did make me think to take a puddle shot but the rain was just too heavy to 1) bother trying and 2) find a still puddle...
So took this just inside the covered entrance of Old Spitalfields Market before checking some of the stalls at the vintage market...
