A lighter tone of Madonna blue. Medici porcelain was the first successful attempt in Europe to make imitations of Chinese porcelain. The experimental manufactory housed in the Casino of San Marco in Florence existed between 1575 and 1587 under the patronage of Francesco l de' Medici, Grand Duke of Tuscany. Following the precedents of classic Chinese blue and white porcelain, decorations were painted in under-glaze blue, which resulted in a range of hues when fired—from a bright cobalt blue to grey

Really an improper name for a specific colour sensation, since Saxon Blue, from which Saxe is derived, is the name of a chemical substance only, a dye from which are produced all tones of blue from light to dark. The word Saxe is not English but is adopted from the French, where it means Saxony or Saxon. Saxony Blue was a universally-used synonym for Smalt as early as 1550. Likewise Bleu de Saxe has long been a synonym for Prussian Blue, but since 1753 Saxon Blue has been most familiar as a widely-used name for indigo extract.
