The song "Pink" by Julia Michaels is about a relationship where the couple shares a love for fitness and the color pink. The singer emphasizes that her partner's love for these things only matters to her if he includes her in his activities and shares his interests with her. The lyrics also suggest a certain level of physical passion between the couple, as they get anxious on days they don't see each other and use "physics" to "fit in their love". Throughout the song, the color pink is a recurring symbol of the couple's connection. The singer sings that her partner "loves the color pink" and suggests that they both wonder if the corridors and doors they walk through are pink. The overall message of the song is that a relationship is more fulfilling when both partners share their passions and interests with each other and make an effort to spend time together.
