Add Color - Slider for Pony / ILXL / SDXL

Key Features:

✅ Works across multiple model types – seamless integration with anime and realism-based models.

✅ Maintains subject integrity – enhances colors without altering anatomy.

✅ Fixes muted colors – ideal for Pony-based realism models that tend to produce flat, desaturated images.

✅ Works in subtle increments – 1.0 - 2.0 is usually enough for natural results, while higher values can create artistic or stylized color effects.

✅ No activation prompt required – simply adjust the slider to increase color depth.
