Trivia: Which country’s islands are famous for their white and blue houses?
The Philippines
Italy
Indonesia
Greece
The correct answer is Greece
So why is this answer correct? : Although the blue and white colors of traditional Greek island homes are those of the national flag, the reason behind the color scheme is less patriotic and more practical. The limestone in the whitewash was once considered a disinfectant and helped to protect against cholera. Meanwhile, the blue was derived from a locally produced talcum powder, and was therefore cheap and readily available.
