Sometimes nature surprises you. What you expect to be one colour is another. Here, a little black and white duck bobbles in a Dublin pond, Herbert Park's ornamental lake.
As he wades through the water, making little rippling waves, the light does something unexpected and we meet hues of silver, white, grey and green in slivers through the chartreuse pond.
In this scarf you see the duck on one side, mirrored on the other by his ripples.
