The song opens with the narrator expressing a sense of wasted time, stating, "I waste my life on looks that I saw you give." This line sets the tone for the entire piece, highlighting the narrator's fixation on the other person's attention and the emotional investment that has not been reciprocated. The repetition of the phrase "I'm not hangin' with ya" throughout the song emphasizes a painful distance, suggesting that the narrator feels rejected and isolated.

As the lyrics progress, the narrator reflects on their identity in relation to the other person, stating, "It's the same old you, the same old me, except you're everything I can't be." This line encapsulates the struggle of self-identity, where the narrator feels overshadowed by the other person's qualities and attributes. The use of the word "everything" indicates a deep-seated admiration mixed with feelings of inadequacy, as the narrator grapples with their self-worth in the context of this relationship.

The chorus further amplifies the emotional weight of the song, with the narrator lamenting, "I guess you'll never know why, I'm not hangin' with ya." This line conveys a sense of resignation and acceptance of the situation, as the narrator acknowledges that their feelings may never be understood by the other person. The repetition of this sentiment throughout the song reinforces the idea of emotional struggle and the difficulty of moving on from someone who has become a central figure in their life.

In the latter part of the song, the narrator expresses a realization of their own limitations, stating, "I can't copy you anymore, think of you anymore, hang with you anymore." This marks a turning point in the narrative, where the narrator begins to recognize the need for self-acceptance and the importance of stepping away from a relationship that has caused them pain. The acknowledgment of not being able to continue in this emotional cycle signifies a desire for growth and healing.

Overall, "Blue" encapsulates the complexities of modern relationships, particularly the feelings of longing, confusion, and the struggle for self-identity. The melancholic tone of the song resonates with anyone who has experienced unrequited love, making it a relatable and poignant piece.

Released in late 2023, "Blue" reflects the contemporary landscape of music where themes of mental health, emotional struggles, and self-identity are increasingly prevalent. PinkPantheress, known for her unique blend of genres and introspective lyrics, captures the essence of modern relationships in a digital age, where connections can often feel superficial and fraught with emotional complexity. The collaboration with producer Sam Gellaitry further enhances the song's ethereal sound, aligning with the current trends in pop and electronic music.
