The History of Colour
Green in Ireland and in Brazil
In Ireland, the green color is associated with its landscapes, the natural color of vegetation that surrounds the countryside, identified as the Emerald Isle. On 17th of March, it is celebrated St. Patrick’s Day, a religious and cultural Irish holiday. St. Patrick, the patron saint of Ireland, is known to have used the shamrock, three-leafed clover to explain the Holy Trinity to pagans. It also represents faith, hope, and love. The four-leafed clover is a popular symbol which came to represent good luck as it is a rare find.
In Brazil, green stands for the extensive nature, fauna and flora that Brazil is home to, specially the Amazon rainforest and the pantanal.The green field, in the national Brazilian flag, represents the Amazon rainforest.
