— A Style Adapter for Injecting Natural Warmth and Cozy Ambiance into Images

Model Overview

This LoRA adapter is designed to generate warm-toned, softly atmospheric visual styles by fine-tuning color distribution and lighting logic. Key enhancements include:

• Warm Lighting Optimization: Automatically simulates color temperatures (2000K-4500K) for sunrise, dusk, and indoor warm lighting, improving natural gradients of orange/gold/amber hues.

• Soft Diffuse Rendering: Reduces highlight sharpness and enhances ambient occlusion, ideal for low-contrast scenes like countryside, interiors, and natural landscapes.

• Emotional Tone Mapping: Incorporates color psychology parameters to evoke warmth, tranquility, and nostalgia.
