Normally, this kind of Medina have white buildings with a fusion of Spanish and Moorish architecture, in the case of Chefchaouen it changes and blue becomes the dominant color.
It is said that the blue color has been introduced to the city by Jewish refugees in 1930, then it caught on, and now many also believe that blue walls serve to repel mosquitoes (mosquitoes do not like the water).
Whatever the reason, the blue of the city walls attract a lot of visitors.
