This quote is saying that making art is a challenge and an expression of emotions. It is like a battle where the artist is trying to get the black charcoal to be balanced with the white paper. The artist’s emotions are expressed through the struggle of combining the dark charcoal and the bright white of the paper to create a balanced composition. This is a metaphor for the struggles of creating art—the effort, passion, and accusation as the artist works to make a statement with their artwork.
