Featuring pastel tones in baby blue stripes and musk pink, No.103 is soft and feminine. The pink tone is naturally and sustainably derived from the purpura patula pansa, a species of sea-snail, picked off the rocks on the coastline at low tide during the winter months. When the dyers squeeze or blow on the mollusks, they give off a foamy secretion which is rubbed onto a skein of cotton. Although it is initially colourless, contact with the air turns it yellow, green, and ultimately purple. The snails are put back on the rocks after this process, which explains why this resource has not been exhausted after so many centuries.
