Feed the first image — a black-and-white manga panel — and the second image — a reference with character colors. The model paints the page while keeping character palettes, hair, eyes, outfits, and overall style consistent. Supports multiple characters in one reference image.Trigger word: <code>mngclranm</code><hr /><h2 id="examples">📊 Examples</h2><img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/8c02949b-5835-46d1-976f-530fec691064/original=true/8c02949b-5835-46d1-976f-530fec691064.jpeg" /><h2 id="extended-description">📖 Extended description</h2>This LoRA is built for manga and comic colorization. You provide a lineart or grayscale page and a color reference showing how characters should look — hair color, skin tone, clothing, accessories, and overall palette. The model fills in the page while preserving line art structure and character identity from the reference.The color reference can include several characters at once (e.g. a colored splash page or character sheet). The LoRA maps those palettes onto matching figures in the target panel.Part of the RefControl family: reference-guided image editing for consistent, controllable generation on FLUX.2 Klein 9B Base.<hr /><h2 id="how-to-use">⚙️ How to use</h2><ol><li>Use the first image as the manga page to colorize (lineart / B&amp;W panel).</li><li>Use the second image as the color reference (colored characters, palette guide).</li><li>Add the trigger word <code>mngclranm</code> in your prompt.</li><li>Optionally add a short text description (lighting, mood, background tint) to refine the result.</li><li>Adjust LoRA weight (recommended 0.8–1.0) depending on how strongly you want to follow the reference colors.</li></ol><h3 id="base-model">Base model</h3>Use with <code>black-forest-labs/FLUX.2-klein-base-9B</code>.
