Show HN: VividManga – AI-based manga coloring focused on line art consistency (vividmanga.com)

VividManga has introduced an innovative AI-based colorization tool specifically designed for manga, enabling users to transform black-and-white artworks into vibrant 4K colors while maintaining line art consistency and preserving dialogue clarity. Users can upload entire ZIP or CBZ archives for batch processing, allowing for quick colorization of 200 pages in approximately 40 minutes. The technology employs a "Character Card" system to ensure character color palettes remain consistent across pages, addressing a common issue with existing colorization tools that often produce mismatched colors. This advancement is significant for the AI/ML community as it streamlines the colorization process, making high-quality visual content accessible to creators and collectors without requiring professional skills. The intelligent text isolation feature safeguards speech bubbles and narration boxes from color bleeds, enhancing the reading experience. By reducing manual labor significantly—reportedly saving users up to 90% of the time typically spent on shading—VividManga sets a new standard in manga colorization, offering not just a tool for enthusiasts but also a resource for professional studios looking to produce high-quality content rapidly.
