Azure means bright clear blue, like a cloudless sky. An azure sky, azure water, deep azure.
It is a poet's and a herald's word — in heraldry azure is the blue, and the shields are described in that language. The origin is a good one: it comes from the Arabic name for lapis lazuli, and the initial l was lost because it was mistaken for the French article.
