Nodes

🎨 Precise LAB Recolor

Single-zone recoloring. Connect a mask + target RGB → recolored image.

🎨 Multi-Zone LAB Recolor

Recolor multiple zones at once. Takes up to 8 masks + a JSON config.

🔍 Auto Color Zone Segmenter

K-Means clustering to auto-detect color zones within a product mask. Outputs up to 8 separate zone masks.

⚡ Batch Colorway Processor

Process ALL colorways in a single pass. Input JSON array of colorway definitions → batch of recolored images.

🎯 RGB Color Input

Parse "R, G, B" strings into individual values.

👁️ Color Swatch Preview

Generate color swatch images for visual comparison.

Workflows

Workflow A: Single-Color Product (e.g., D4T Knit Pant)

┌─────────────┐     ┌──────────────┐     ┌─────────────────┐     ┌──────────┐
│ Load Image  │────→│  SAM Segment │────→│ 🎨 Precise LAB  │────→│  Save    │

└─────────────┘     └──────────────┘     │                 │     └──────────┘

                                          │ lum_blend: 0.6  │
                                          └─────────────────┘

Steps:

1. Load source product image
2. SAM: Click on the pants → generates mask
3. Precise LAB Recolor: Set target RGB from colorway spec
4. Save / preview

Workflow B: Multi-Zone Product (e.g., 3-Stripes T-Shirt)

┌────────────┐     ┌──────────────┐
│ Load Image │────→│ SAM Segment  │──→ mask_0 (main body)
│ (JD1906)   │     │ (3 clicks)   │──→ mask_1 (stripes)
└────────────┘     └──────────────┘──→ mask_2 (logo)

                   │ zone_config JSON │
                   └──────────────────┘

zone_config for JX0732 (Turqoise):

[
    {"mask_index": 0, "r": 88, "g": 148, "b": 134, "label": "Main"},
    {"mask_index": 1, "r": 4, "g": 0, "b": 0, "label": "3 stripes"},
    {"mask_index": 2, "r": 4, "g": 0, "b": 0, "label": "Logo"}
]

Workflow C: Complex Multi-Zone (e.g., TIRO25C Jacket, 7 zones)

┌────────────┐     ┌──────────────┐
│ Load Image │────→│ SAM Segment  │──→ 7 masks (one per zone)
│ (TIRO25C)  │     │ or Auto Zone │
└────────────┘     └──────────────┘
                          │
