Valentine's Day themed image with a black cat silhouette, contemporary pop art style. Utilize bold, bright colors like yellow, blue, pink, and green to create a series of four panels, each with a different color scheme. The black cat silhouette should remain the focal point in each panel, but the surrounding hearts and background should be adapted to fit the pop art aesthetic. Think about incorporating contrasting colors, repetitive patterns, and a playful, energetic vibe to each panel, capturing the essence of pop art's dynamic and vibrant nature. --s 750
