Easily pleased- love the colours

Just finished work. Ran out coat flying, scarf thrown round neck, phone in hand and actually switched on, when I found a gap in the traffic, jumped across a puddle, saw bus coming along road. Hurray - no waiting. Looked down and saw these markings on road. I had time to switch phone to camera mode, let it focus - take one snap, and then get onto bus, even finding an empty seat at back of bus - (school about to start, and the others who were fresh and about to start their day (although the combined smell of deodorants, aftershave and perfumes was overpowering). I have stood at this bus stop after work for over a year, but have never noticed them.It reminds me of a symbol, but I cant remember what it means. The colours made me feel good (or it could be that I'm now off work until Wednesday). I was exhausted when I first went out, but as the chill began to bite- the scarf went round the neck properly, then the coat fastened, and finally the gloves were on as I walked through the city centre, looking for blips. I currently am wide awake at home wondering what to do next.
