Eclat de saphir (Sapphire blue): sapphire is a gemstone. The terminology probably comes from 2 origins: the Greek with “sappheiros” (a stone of blue color) or from the Hebrew “sappir” (the most beautiful thing). This color is a reminder of J. Herbin and his work at the most prestigious royal courts of Europe.
