Blue is a color that has long been associated with royalty, art, military, business and nature, making it a color with a lot of applications. The first documented use of blue pigment is using blue azurite, a vivid deep blue naturally occurring mineral, used widely in ancient Egypt for decoration and jewelry. Later, in the Renaissance, the mineral was crushed and used as the expensive paint pigment ultramarine.
Blue is a versatile colour that matches well with most coat colours, and compliments most horses well. It is easy to match with other shades and contrasting colours too!
