由 Flux Kontext Dev 生成的 FLUX AI 图像

Replace the monster in the center with only its silhouette outline at the exact same position and size. The outline should be a single continuous line, rainbow-colored (red, orange, yellow, green, blue, indigo, violet). No fill inside — hollow, transparent silhouette. Keep all other parts of the image unchanged. Background must be pure white, no texture, no shadows.
