Anima Style Tweaker - Saturation, Contrast, Temperature / 饱和度, 对比度, 色温

Anima Style Tweaker (Experimental)

This is an experimental tweaker/slider LoRA inspired by IL Slider | Tweaker — Color Temperature, Saturation, Brightness by Akiseki, which was my most-used LoRA back in my SDXL days.

Saturation(饱和度)

Contrast(对比度)

Temperature(色温)

Discussion

I've tried many approaches, but none of them matched the performance of the original IL Slider. For this version, I used difference-based training (training on paired images that differ only in the target attribute), then applied block masking and orthogonalized the weights across the different axes (contrast, saturation, brightness) to keep them independent. Despite all that, it still slightly contaminates the composition.

This is the current experimental release — there are still plenty of issues, and I'd really appreciate any feedback or suggestions!
