The lyrics to ギルガメッシュ's song Vermillion express the conflicting emotions and thoughts of the narrator, who feels trapped by their own uncertainty and the opinions of others. The first verse describes the narrator's frustration with their inability to speak out, as they feel unable to express themselves or their inner turmoil. They are aware of the judgment and ridicule of those around them, including an unknown presence that seems to watch and judge their every move.

The second verse delves deeper into the narrator's psychology, as they question their own motives and struggle to reconcile their desires with reality. They feel that their own will has been buried and muddled by the opinions of others, and that they are simply copying or imitating what they see around them. They wonder why people are so prone to doubt and uncertainty, and why they themselves cannot simply enjoy the good things in life without feeling the weight of their own contradictions.

The chorus repeats the phrase "the voice that blocks out the light," a reference to the narrator's state of mind and the obstacles that prevent them from moving forward. They long to be left alone and to find a way to end their struggles once and for all, but recognize that this may not be possible. The final line, "what do I understand?" highlights the narrator's sense of confusion and isolation, as they struggle to make sense of their own existence in a world that is both beautiful and cruel.
