What it is¶

FLUX.2 Klein 9B Manga Colorization LoRA is a LoRA adapter for artists and ComfyUI or Diffusers users who transfer character palettes from a color reference onto line art or grayscale panels.

• Palette matching for hair, eye, clothing, and skin tones.
• Multi-character support on a single reference image.
• Prompt guidance for lighting and background tweaks.

Development line¶

• 2026-06-10 — Hugging Face model reference recorded for the project. We recorded the Hugging Face model repository for the FLUX.2 Klein 9B manga colorization by reference LoRA on 2026-06-10.

What changed¶

2026-06-10 — The initial Apache-2.0 adapter repository was published for FLUX.2 Klein 9B Base; it sets trigger mngclranm and specifies the base model. 2026-07-05 — A third-party ComfyUI workflow showed batch colorization for a folder of pages against a separate color reference; this is a community integration, not a new LoRA version.

How to use this¶

As of 2026-06-10, treat the linked Hugging Face LoRA as a reference workflow. Verify its capabilities, compatibility, licensing, and usage instructions before adoption.

1. Load black-forest-labs/FLUX.2-klein-base-9B, then connect the adapter weights with load_lora_weights or Load LoRA in ComfyUI. — https://huggingface.co/thedeoxen/FLUX.2-klein-9B-manga-colorization-by-reference-LORA
2. Provide the black-and-white page as the target image and a separate colored character sheet, cover, or splash page as the reference. — https://huggingface.co/thedeoxen/FLUX.2-klein-9B-manga-colorization-by-reference-LORA
3. Add mngclranm to the prompt; add lighting, mood, or background notes if needed. — https://huggingface.co/thedeoxen/FLUX.2-klein-9B-manga-colorization-by-reference-LORA
4. Start with a LoRA weight of 0.8–1.0; reduce it if color transfer becomes excessive. — https://huggingface.co/thedeoxen/FLUX.2-klein-9B-manga-colorization-by-reference-LORA

Best practices¶

• Pick a clean reference where page characters are clearly visible; a cover or character sheet works for multiple figures. — https://huggingface.co/thedeoxen/FLUX.2-klein-9B-manga-colorization-by-reference-LORA
• If character colors blend, change the seed first; then clean the reference or split the page into smaller panels. — https://www.reddit.com/r/comfyui/comments/1uo52jb/comfyui_manga_colorization_with_color_reference/
• In ComfyUI, keep the target page larger than the reference: running about 1.5 MP against 0.5 MP reduced reference composition bleed in shared tests. — https://www.reddit.com/r/comfyui/comments/1uo52jb/comfyui_manga_colorization_with_color_reference/

Superseded by this¶

• Nothing marked obsolete yet.

Still unknown¶

• The repository card describes a two-image reference workflow, but its generic Diffusers widget example shows only one input image; the exact public Diffusers call for supplying the second color-reference image is not documented there.
• No first-party changelog or later model revision was found after the initial 2026-06-10 commit; the 2026-07-05 item is community workflow evidence, not a LoRA release.
