Broadly speaking, the Renaissance unfolded during the 15th century (quattrocento) and 16th century (cinquecento). The Early Renaissance (c.1400-1490) was followed by the High Renaissance (c.1490-1530), which in turn was succeeded by Mannerism (c.1530-1600). During this period, although painting techniques - which encompassed everything from linear perspective, foreshortening, and sfumato to Tenebrism and chiaroscuro - improved immeasurably, as did the theory and practice of colourism, only two new pigments emerged. A synthetic version of Naples Yellow was produced, and a number of Red Lakes were developed.
