Bicycle Color Layer Creation

I have three clean studio shots of the same bicycle model already saved as TIF files. What I need is a tidy, reusable colour-change setup for each model so I can show the bike in all twelve of our catalogue colours.

Scope
• Only the frame and fork should shift hue; wheels, tyres, bars and every other component stay exactly as they are.
• I’ll supply the precise colour codes (HEX/Pantone) for the twelve finishes.

Deliverables
1. Color layer PSDs returned, twelve per bike model.
2. Twelve non-destructive colour layers/groups, properly masked to the frame and fork.
3. A brief note explaining any smart-object or clipping-mask structure you used so future edits are simple.

Acceptance criteria
• Colours match the supplied codes within standard sRGB tolerance.
• Edges are crisp with no spill on neighbouring parts.
• File size remains reasonable (no unnecessary rasterised duplicates).

I can give examples of same project on the previous model as reference.
That’s it—let me know your turnaround time and any questions about the files before you begin.
