The official description of the colour is "a very pale icy pastel cyan".
The Queen is wearing a creation by Angela Kelly – her senior dresser – comprising a dress of mint green fine silk tulle, upon which tiny star shaped flowers have been embroidered, then embellished with silver thread. A mint green chiffon drape, scattered with Swarovski crystals on the shoulders, has been added, which sweeps over the shoulders and down the back of the coat. The crown of the hat is covered in the same tulle and has also been draped in mint green chiffon and Swarovski crystals.
