While studying fine arts, the group learned about color theory and chose the color violet to represent the band's themes. Rainbow said in an early interview: "Violet is the color of the tragic comedy. We associate it with fantasy and melancholy. These themes make up much of the band's lyrical inspiration. The color also mirrors our sound dynamic. Our music mixes contrasting elements. In turn, violet is the sum of two contrasting colors: Red and Blue." The band established their signature sound and visuals during this time and later when they signed to their labels retained complete artistic freedom.
