Use screen colour to explain direction
HEX values and 3D previews help compare combinations. Include the visual reference and explain transparency, gradients and component matching. The screenshot should communicate direction rather than serve as the only acceptance reference.
Create references for each component
Identify a colour reference for each component and review them in the assembly. Different materials and surfaces may produce a different appearance. Agree where a coordinated match is required and how any acceptable variation will be assessed.
Retain one approval set
Keep the sample identity, parts, colour references, finish and artwork revision together with the viewing conditions. Reconfirm affected references after changes. The approval set should be usable by the next repeat-order team without relying on a private chat history.
Your Project Checklist
- Record colours by component
- Agree physical viewing conditions
