Or... every shade of blue in this town...
Every corner you turn, you see the walls and arches and ceilings and ground painted blue. It's unbelievable and dreamy!
Why is everything painted blue? I did a little research.
Even though Morocco is now 99% Muslim, this blueness has a Jewish origin. It is a medieval remnant from the late 15th century exodus from Europe during the Spanish Inquisition, which nobody ever expected. Chefchaouen was a refugee camp with many Jews, and they painted their buildings blue as a sign of God's power above.
