Why “PVD” does not define a colour
What this resource changes in your next decision, and the evidence behind it.
Takeaways
- PVD names a coating family, not a colour: the colour comes from the process gas, the layer stack and the target used.
- A colour agreed by name alone cannot be repeated; the target has to be a physical sample approved under a stated light source.
- Thickness, under-layer and edge break decide how the colour ages, not the PVD label on the quotation.
The problem it answers
Evidence and limits
Based on our own plating route records and colour approvals for steel chains. It states what belongs in a specification; it is not a testing service or a certification.
