Venice and Florence were powerful city states during the time of the Italian Renaissance. Venice was a port city which meant that all the exotic wonders of the world could be found there. This lead to experimentation with color that other European cities couldn't come anywhere near to emulating. Color was such a huge part of Venice that people created whole businesses that involved the making and developing of pigments and dyes. It is no wonder that Venetian art was known for its "colorito" approach.
