Moroccan architecture is known for their vivid and colourful design. But what do they mean? After some research I found that: The Blue represents Sky, Heaven, Water and Protection; The White represents cleanness, good luck, beauty and femininity. Red is female, sexuality, fertility, childbirth and also relates to a happy marriage. Green relates with the Muslim interpretation of heaven (a green oasis), and lastly Yellow relates to gold, wealth, sun and protection. The colour symbolism of each is not very different from our own colour symbolisms. However, when we observe these colourful and beautiful tiles, combining these colours in unique ways, it is important to remember what they mean and the complex message that they really convey.
