The Sistine Chapel in the Vatican has many frescoes painted in it, yet is most famous for the frescoes on the ceiling by Michelangelo. Extensive restoration was done between 1980 and 1994 by Vatican art experts, removing centuries' worth of smoke from candles and previous restoration work. This revealed colors much brighter than previously thought.
Pigments Michelangelo used included ochre for reds and yellows, iron silicates for greens, lapis lazuli for blues, and charcoal for black.1 Not everything is painted in as much detail it first appears. For instance figures in the foreground are painted in more detail than those in the background, adding to the sense of depth in the ceiling.
