Pollera colora' literally translates to "red skirt." While pollera can mean skirt, in Colombian culture, a "pollera colorá" specifically refers to the vibrant, full skirt worn by women in traditional cumbia dances.
In the song, the lyric "Hasta que se te ponga la pollera colora'" (Until your skirt turns red) is a playful and culturally rich way of saying "until you're dancing so hard and sweating so much that your skirt looks red from the effort." It evokes the energetic and passionate spirit of Colombian cumbia and invites listeners to fully immerse themselves in the music and dance.
Li Saumet spends most of this song repeating one instruction: Fuego, no lo dejes apagar (Fire, don't let it go out). It reads less like a metaphor than like a job. The fire is the party, and somebody has to keep feeding it.
Between the choruses she lists what the band actually is, Un poco de folclor con música electrónica (a little folklore with electronic music), and then introduces herself by ruling out everyone she isn't, which is a funny way to do it: Y si tú no me conoces no me llamo Camila (and if you don't know me, my name isn't Camila), a couple of names later landing on Me llamo Li Saumet, de la fiesta soy la dueña (my name is Li Saumet, and this party belongs to me). Her claim to it is geographic. Yo crecí tomando, agua de panela helada (I grew up drinking ice-cold panela water), she says, in a place where cold is not really a thing. The goal for the night is stated just as plainly: Hasta que se te ponga la pollera colora' (until your skirt turns red), borrowing Colombia's most famous cumbia image to mean keep dancing until you are flushed.
