"The Eiffel Tower in Paris, France 
is repainted every seven years 
with about 60 tons of paint 
at the cost of about $20 million dollars. 
The specially chosen colors 
are named Eiffel Tower brown numbers 1, 2 and 3 
as there are three shades of brown 
to emphasize the shape of the tower 
 as seen from the ground 
-the lightest shade at the top, 
and the darkest at the bottom."
