AI Tech Pack Color Specification: Pantone, Lab Values, and Colorway Management
How to specify colors in AI tech packs — Pantone references, lab values, colorway management, and ensuring color consistency from spec to production.
Why color specification matters
Color is the number one source of production disputes in fashion. 'Navy blue' means different things to different factories, different fabric suppliers, and different dye houses. Without precise color references in your tech pack, you will receive samples that do not match your intent.
An AI tech pack from Skema3D includes color specification sections with appropriate reference systems based on the colors and materials you describe. The AI generates structured colorway information that eliminates ambiguity.
Color reference systems
Different color reference systems serve different purposes in tech packs.
Color reference systems for AI tech packs
| System | Format | Best For | Limitations |
|---|---|---|---|
| Pantone TPX/TCX | Color number (e.g., 19-4052 TCX) | Fabric and textile colors | Physical swatch needed for exact match |
| Pantone C/U | Color number (e.g., 289 C) | Print colors on paper/packaging | Not accurate for fabric colors |
| CIELAB (L*a*b*) | Numeric values (L, a, b) | Objective color measurement | Requires spectrophotometer |
| Hex/RGB | #1A2B3C / R:26 G:43 B:60 | Digital/screen reference | Not reliable for physical production |
| Physical swatch | Approved fabric or trim swatch | Exact production matching | Subject to fading, not scalable |
Managing colorways in AI tech packs
Most garments are produced in multiple colorways. Your AI tech pack should specify each colorway completely — not just the body color, but the color of every component: body fabric, rib trim, zipper, thread, labels, and hardware.
When you tell Skema3D 'create 3 colorways: black, navy, and forest green,' the AI generates a complete color specification for each colorway, including coordinating trim and hardware colors. This ensures that when you say 'black colorway,' the factory knows the rib, thread, zipper tape, and labels should also be black (or whatever contrast you specify).
Color tolerance and approval
Your AI tech pack should include color tolerance specifications — how much deviation from the reference is acceptable. Standard tolerance is Delta E (ΔE) of 1.0-1.5 for critical colors. Wider tolerances (ΔE 2.0-3.0) may be acceptable for less visible components like pocket lining.
- Critical colors (body fabric, visible trim): ΔE ≤ 1.0-1.5
- Secondary colors (lining, internal): ΔE ≤ 2.0-3.0
- Color matching between fabric and trim: ΔE ≤ 1.5
- Lab dip approval: require lab dip approval before bulk dyeing begins
Color specification workflow
Start with your AI tech pack from Skema3D at /ai-tech-pack-generator, specifying color names and any Pantone references you already know. The AI generates a structured colorway section. Before production, supplement with physical lab dip approvals to confirm the color matches on your actual fabric.
The AI tech pack gives you the specification framework — lab dip approval gives you the physical validation. Both are necessary for consistent color in production.
