The following quote from Lloyd is a good reminder of what we love about the color blue. It is prized by the artist, and I will add that French Ultramarine is the easiest color to form into pastel sticks, and my yummiest single color.
Blue. The noble color of the sky.
Blue has always been associated with royalty, it is cool, soothing, a reminder of infinity and things spiritual. It gives a sense of stability. It is no co-incidence that big financial institutions often have blue colored emblems.
Although the sky and the sea are both rich in blues, blue coloring is rare in natural minerals, Azurite and Turquoise being almost the only ones used for art until modern times. Ancient Britons covered their faces in Woad, and around the Mediterranean Indigo was used for dyeing textiles. The scarcity of good and affordable blues meant both were employed by artists from time to time. The Egyptians developed Blue Frit to meet the need for a good blue but it was too weak and coarse to last until modern times.
When the Europeans began importing ground Lapis Lazuli they thought they had found the perfect blue finally. It was except that it cost more than the same weight of gold. It wasn't until the synthesization of Ultramarine in the 1820's that artist had what they really needed all those years, an affordable, permanent, and useful deep blue of great beauty.
