Retrovisor is the Spanish word for a car's "rearview mirror". It's a fantastic word that goes beyond its literal meaning in this song.
Lasso sings, "en el retrovisor, imágenes de ti" (in the rearview mirror, images of you), using it as a powerful metaphor for looking back at a past relationship. Even while driving forward in his life, he can't escape the memories of his ex that linger like a reflection.
Ever been on a date that is technically perfect, but your heart just refuses to cooperate? That is the exact trap Venezuelan pop singer Lasso and Colombian guest Sebastián Yatra find themselves in on "Ojos Marrones". The singer takes a new girl to the same old restaurant, and on paper, she ticks every single box: "a ella sí le dan risa mis chistes" (she actually laughs at my jokes), she gets along with his friends, and they never argue. There is even a nod to the classic Spanish proverb "un clavo saca otro clavo" when Yatra sings, "Dicen que se supera / Un amor con otro amor" (They say one love gets over another love). Everything should be great. Except it isn't.
The entire track pivots on one stubborn detail: her gaze. Her eyes might shine like gems—"Ella tiene los diamantes para mirar" (She has diamonds to look with)—and they are bright blue, but "sus ojos azules no son tus ojos marrones" (her blue eyes are not your brown eyes). Even the ocean loses its shade and the rear-view mirror only reflects memories of the ex. The song turns a supposedly boring eye color into an obsession, showing that someone can be flawless on paper and still lose to a lingering memory.
