Catholicism spread their regionalized interpretations of Jesus and other important figures, for example the virgin Mary is represented with attributes similar to those of the locals as well as the colors of the country flag.

In Mexico we have the Virgen de Guadalupe, she’s “morenita” (light brownish skin) and she’s wearing a green robe, she has a red aura around her and she’s on a white ish background, similar to the Mexican flag 🇲🇽

In Argentina they have the Virgen de Luján, she’s wearing a light blue robe and her hands suddenly pop out of her robe right in the middle of her body, simulating the structure of the Argentinian flag 🇦🇷

In Venezuela, they have the Virgen de Coromoto, wearing a blue robe, red pants and she’s under a yellow structure, once again, similar to the country flag. 🇻🇪

They used the virgin here as LATAM countries are centered around respect for one’s mother, so normally you can find people calling the virgin as they would their mother, and then you sprinkle the flags colors for further identification.
