MAGICMATCH

ComfyUI custom nodes for neural color match: two images in, graded source out. Tune strength on a preview node before you wire the result to save/export.

Install

1. Clone into ComfyUI custom_nodes:

   cd ComfyUI/custom_nodes
   git clone https://github.com/lookuters22/MAGICMATCH.git
   

2. Install Python deps (ComfyUI’s environment):

   pip install -r MAGICMATCH/requirements.txt
   

3. Confirm the model file is present:

   MAGICMATCH/models/color_match.onnx
   

4. Restart ComfyUI. Nodes appear under MAGICMATCH.

Workflow (strength before export)

Use Build + Preview so changing the slider only re-applies the LUT (fast):

[Source] ──┬──► MagicMatch Build LUT ◄── [Reference]
           │              │
           │              ▼ lut
           └──────► MagicMatch Preview (strength) ──► Preview Image
                                         │
                                         └──► Save / export when ready

Step	Node
1	MagicMatch Build LUT — run once per source/reference pair
2	MagicMatch Preview (strength) — run once, then use the live preview inside the node and drag strength (no re-queue)
3	When happy with the slider, Queue again and connect output to Save / export

In-node live preview

1. Run the workflow once (Build + Preview execute; LUT is cached).
2. Open the MagicMatch Preview node — you’ll see a live image under the widgets.
3. Drag strength — preview updates instantly in the node (WebGL, no workflow re-run).
4. When the look is right, Queue Prompt once more so the image output matches the slider, then save/export.

Live preview uses WebGL (merged 25³ LUT + strength mix). Mid-strength may differ slightly from the queued image output, which uses the full CPU path — queue once more before export.

MagicMatch (one-shot) combines build + apply in one node (simpler, slower when you change strength).

Requirements

• ComfyUI with standard IMAGE tensors (batch size 1)
• onnxruntime, numpy (see requirements.txt)
• CPU inference by default (~5–15s for Build on first run per pair)
