The song "De Cor" (By Heart) by Lulu Santos is about the feeling of experiencing something familiar as if it were new or the first time. The lyrics describe the sensation of opening the front door, hearing familiar steps and greetings, and smelling a certain perfume, as if for the first time. The song also talks about the feeling of restlessness, old fears, and desires, as well as whispers and laughs, all feeling like the first time. Santos also sings about physical sensations, such as the feeling of a kiss, the body's hair, and the light and dark marks of a sunburn. These sensations make the singer feel like he is losing his senses in the middle of the vapor or steam. Overall, the song talks about the experience of going through familiar situations, but feeling as though they are happening for the first time. It is a reflection on the power of memory and the ability for certain moments to feel fresh and new, even when they are not.
