37 shades of grey provide evidence, grey can be much more than a colour between black and white. Grey, mousy, stone and blush grey, the swarm of carrier pigeons, designed by TERA1 and JAYB are different, but not that much. They come together in a grey matter, except for that one and only pink one. It stands out of the grey mass of uniform as an individual. A colourful bird, clearly visible and well embedded in the swarm.
