Blending - Style

Blending - pictures where the background and foreground, or otherwise two separate items blend together due to having the same colour with no border to separate them.

Commonly done with the character's hair being the same hue as the solid colour backdrop.

A possible result of no lineart and flat color - see: Flat Color - Style

ℹ️ LoRA work best when applied to the base models on which they are trained. Please read the About This Version on the appropriate base models and workflow/training information.

Recommended prompt structure:

Positive prompt:

blending, flat color, no lineart, negative space, {{tags}}, {{color}} background

Description

Trained on Anima Base 1

Updated dataset, and partitioned by resolution for multi-resolution training.

Using captions.json with 16 mixed tag/natural language variants with tag dropout and shuffle.

Training config:
