What kind of paint did they use to paint the Eiffel tower?

The Eiffel Tower has been painted in a number of different colors throughout its history, but today, it is painted a color called "Eiffel Tower brown," which turns out to be the color of Milk Chocolate, and it is used in three very slightly different shades at different elevations of the tower (higher elevations use a lighter shade), in order to accentuate the impression of height. The paint is synthetic, lead-free, and silicone-based, and the entire structure is repainted over a period of 6-7 years by several dozen fearless and highly acrobatic painters, by hand (no automated way of painting the tower has ever been satisfactory). The most recent repainting operation (the nineteenth) began in 2009 and required about two years.
