Urban life developed in the 1st millennium BC. Capital cities were born (Athens and Rome). Prestigious monuments were built: temples, palaces, lavish mansions… All these buildings were decorated and coloured with frescoes, mosaics and hangings. The statues which decorated them were set off with colours. Painting in Antiquity used numerous pigments : black, white, red, yellow, blue and green. Antiquity should be imagined in technicolor !
