The Word "Pink" Wasn't Originally A Color
No one called anything "pink" until the mid-nineteenth century. Before it was a color, the word pink meant a young salmon or a sword-fighting wound. It also referred to pinking shears. The pink dianthus flower has scalloped edges, which is the pattern that pinking shears make. The color of this flower (pink) was named after those specific scissors.
