Civilisations - Season 1 Episode 7

Throughout art history, achieving radiance by color and light interacting has played major part. Colorite has its own history, linked to the symbolical meaning and material composition of pre-industrial natural (mineral, vegetal or animal) pigment ingredients, sometimes as precious and exotic as Afghan lapis lazuli (for ultramarine), often traded from the Orient, contributing to the wealth and artistic prowess of Venice. On the other hand, claire-obscure dominates certain traditions, notably Gothic architecture suggesting uplifting toward Heaven, which combines it with radiant stained glass and artists, like El Greco's dark depiction of grim times.
