Sparks: the lyrics rip it off as slowly as they can, prolonging the pain you feel as you begin to feel your smile pull tightly at your skin. It’s a song that is more deeply filled with immense regret and longing. One filled with internal sadness and desperation. The lyrics focus on the character of the song dealing with his partner leaving him and emphasize how hurt he is knowing he hurt his partner, pushing her away until she had no choice but to leave.
Yellow: The song’s lyrics describe all the things some more ridiculous than others a person will do to express their love and devotion for someone: write a song, swim and jump across obstacles, draw a line, and even sacrifice their life. "Yellow" is a term that can mean cowardly or afraid. From this standpoint, the singer could be afraid and nervous to show his love, until he "ran across" and "jumped across" for her. He finally got the nerve to express his love.
