ColoringBook.Redmond 2.1V – Coloring Book LoRA for Stable Diffusion 2.1

TL;DR

What this model does

ColoringBook.Redmond 2.1V is a Low-Rank Adaptation (LoRA) trained on stabilityai/stable-diffusion-2-1-base that steers generations toward a coloring-book aesthetic: bold, clean lines, minimal shading, and open areas ready for color fill. It was created by ArtificialGuyBR and released on Hugging Face.

The model card shows example outputs across a range of subjects — animals (owl, lion, fat cat), characters (superhero, pirate boy, portrait of an asian woman), patterns (mandala), and vehicles (Ferrari) — all sharing the same consistent line-art style.

How it was trained

The author does not publish the exact training dataset size, learning rate, or step count on the model card.

How to use it

With 🧨 diffusers (Python)

from diffusers import AutoPipelineForText2Image
import torch

pipeline = AutoPipelineForText2Image.from_pretrained(
    'stabilityai/stable-diffusion-2-1-base',
    torch_dtype=torch.float16
).to('cuda')

pipeline.load_lora_weights(
    'artificialguybr/coloringbook-redmond-2-1v-coloring-book-lora-for-freedomredmond-sd-2-1',
    weight_name='ColoringBookRedmond21V-FreedomRedmond-ColoringBook-ColoringBookAF.safetensors'
)

image = pipeline('A cute owl, Coloring Book, ColoringBookAF').images[0]
image.save('owl-coloring.png')

Prompt format

Always include both trigger tokens:

<your subject>, Coloring Book, ColoringBookAF

FAQ

Q: Does this work with SDXL or SD 1.5? A: No. It was trained specifically on SD 2.1 base. Using it on other base models will produce poor results.

Q: Can I merge this LoRA into the base model? A: Yes, diffusers supports fuse_lora() for permanent merging. See the diffusers LoRA docs.

Q: Is there a Civitai page? A: Not linked from the Hugging Face model card. The model appears to be HF-only.

Q: What resolution works best? A: SD 2.1 base is natively 512×512. For higher resolutions, use hi-res fix or upscale after generation.
