Cobalt blue and its importance in Portuguese tiles.

The significance of cobalt blue in azulejos lies in its association with the prestigious Chinese porcelain and its evolution in the painting of Portuguese tiles from the late 17th century. 

This color became prominent, often used in combination with white, and played an important role in the aesthetics and evolution of tile art in Portugal. Its popularity endures to this day, being considered a fashionable color for home painting and a lasting trend. Additionally, cobalt blue also played a revolutionary role in Chinese ceramics, being one of the most well-known tones in blue and white porcelain. Therefore, the importance of cobalt blue in azulejos is rooted in its history, influence on art and design, and its enduring aesthetic appeal. This color scheme has become prominent due to the influence of the Mudejar-style tiles, which King Manuel I of Portugal discovered in Seville, Spain, in 1498. Blue and white tiles have become a distinctive feature of tile art in Portugal and are widely used in the decoration of buildings, churches, and monuments throughout the country. The popularity and durability of these colors have contributed to their prominence in Portuguese tile art and culture.
