Eric Color Correction for ComfyUI

Professional color correction, skin masking, and batch utility nodes for ComfyUI.

This custom node pack focuses on practical skin-tone workflows:

• Analyze skin line angle and luminance against targets.
• Remove color cast with skin-guided white balance.
• Correct skin hue and luminance selectively.
• Build masks from face parsing, human parsing, and MediaPipe landmarks.
• Reuse correction values across image batches.

Highlights

• Production-oriented tools for people-centric imagery.
• Works with batch image pipelines.
• Supports workflow combinations with custom masks.
• Includes multiple segmentation/masking paths for different quality and speed tradeoffs.

Included Nodes

See requirements.txt for baseline dependencies and pyproject.toml for packaging metadata.

Installation

Option 1: ComfyUI Manager

1. Open ComfyUI Manager.
2. Search for this node pack.
3. Install and restart ComfyUI.

Option 2: Manual Install

1. Clone this repository into your ComfyUI custom_nodes directory.
2. Install dependencies:
   • pip install -r requirements.txt
3. Restart ComfyUI.

Example custom_nodes path:

• ComfyUI/custom_nodes/Eric_Color_Correction

Quick Workflow Pattern

1. Generate or load an image.
2. Build a skin mask with one of:
   • FaceParsingSkinMask
   • HumanParsingSkinMask
   • MediaPipeSkinMask
3. Run ColorCorrectionAnalyzer to inspect skin line deviation and luminance.
4. Apply ColorCastRemover for white balance cleanup.
5. Apply SkinToneCorrector and/or SkinLuminanceAdjust.
6. Re-check with ColorCorrectionAnalyzer.
7. For batch pipelines, reuse values with ApplySavedCorrection.

Troubleshooting

Missing model or import errors

• Confirm required dependencies are installed.
• Restart ComfyUI after dependency changes.

Slow first run

• Some parsing nodes load models on first execution.
• Subsequent runs are typically faster due to model caching.

CUDA memory issues

• Reduce batch sizes.
• Use lower-resolution previews for correction tuning.

Versioning and Releases

• Keep release notes in CHANGELOG.md.
• Tag releases using semantic versioning where possible.
• Include screenshots or example workflows in release notes for better discoverability.

Publishing Checklist (GitHub)

• Ensure .gitignore excludes local runtime and sensitive files.
• Confirm README, LICENSE, and dependency documentation are up to date.
• Verify pyproject.toml metadata (name, version, contacts, URLs).
• Run a quick import smoke test before creating a release tag.
