Why jaipur called pink city?

Jaipur is called the "Pink City" because of the distinct color of its buildings, which were painted pink in 1876 to welcome the Prince of Wales, Albert Edward. This color was chosen to symbolize hospitality and has since become a defining characteristic of the city's architecture. The vibrant hue can be seen throughout Jaipur's historic structures, including the Hawa Mahal and the City Palace, contributing to its unique charm and identity.
