The town of Purmamarca in Northern Argentina is famous for its Hill of Seven Colors (Cerro de los Siete Colores).
Legend has it that the children of the village painted the once-dull hill at night while their parents slept. Each night they painted one color, and after 7 nights they completed their masterpiece. Every year the townsfolk of Purmamarca have a celebration in honor of the painting of the hill.
Scientifically, the different colors were formed by various types of claystones, mudstones, limestones and other types of rocks during different time periods. Overtime they resulted in the ochre, yellow, orange, green, brown, lilac and violet colours of the hill we see today.
