The letter "C" appended to the title suggests this is one of several variations on the twilight theme, with Saito exploring different aspects of the transitional hour between day and night across multiple prints. Twilight's defining quality is its shifting, unstable light, a condition that changes minute by minute as the sun drops below the horizon and the sky cycles through its color sequence. Saito's woodblock rendering must fix one moment of this progression into a permanent image, choosing a specific point in twilight's arc to commit to paper. The print likely explores the tonal range available at that liminal hour, when shadows deepen and colors lose their daytime saturation but have not yet surrendered entirely to darkness.
