Red bathed the small Panamanian town of Portobelo on Saturday in a celebration meant to represent a fight between good and evil, and the resistance of slaves and Spanish colonizers. Every year, hundreds in the town, which sits wedged between the Caribbean Sea and the region's tropical jungles, take to the streets for the Festival of Devils and Congos. The festival uses dramatic imagery and bright colors characteristic of Caribbean celebrations to capture the historic struggle between slaves during the time of colonization.
