The altar of Zeus is an impressive sight, made of white marble and decorated with intricate reliefs depicting scenes from Greek mythology. Make each sculpted figure and detail of the reliefs stand out with shades of light and dark gray, stone, cream, and ivory, and bring Zeus himself to life with shades of gold and forest-green. The bowl on the altar should be made brimming with offerings to the gods in hues of yellow, ruby and sapphire, while the altar itself could be given a timeless classical feel with hues of ivy-greens and lavender picking out the details. Finally, bring the whole scene to life with accents and shadows of deep purple, navy, and emerald.
