01
Component harmony
Control adjoining parts so small material differences do not become obvious after assembly.
Products & components
Color control for consumer products & components
Standardise component and finished-product color across plastics, coatings, packaging and supplier networks—before mismatched parts reach assembly.
Why color drifts
The customer sees one product; manufacturing sees many materials.
A finished product can combine moulded plastics, painted metal, soft-touch coatings, labels, textiles and transparent parts from different suppliers. Matching those surfaces requires a common visual target, material-specific measurement methods and a final assembled-product check.
02
Supplier consistency
Share standards and methods across moulders, coaters, converters and contract manufacturers.
03
Launch protection
Approve color at design, tooling, pilot and production stages before volume amplifies a mismatch.
Instrument options
Portable and benchtop instruments for Consumer Products
Portable instruments support supplier, line-side and finished-product checks. Benchtop instruments support controlled laboratory standards, small components, liquids, transparent materials and fixture-led QA.
Where it pays off
Use cases across the product lifecycle
01
Design standards
Convert approved visual intent into measurable master and working standards.
02
Incoming components
Check supplier parts before they enter assembly or contaminate a production lot.
03
First-off approval
Verify color after moulding, coating or finishing changes at line start.
04
Assembly matching
Compare adjacent components in the orientation and lighting customers will see.
05
Packaging coordination
Align product, label, closure and carton color where the system is sold together.
06
Claims & troubleshooting
Use spectral and component data to separate pigment shifts from gloss, texture or process effects.
Method notes
Decisions that make measurement repeatable
| Decision | Common starting point | Why it matters |
|---|---|---|
| Material | Define a method for each optical behaviour | Opaque, translucent, glossy and textured parts cannot always share one presentation method. |
| Location | Mark repeatable measurement zones | Curves, ribs, gates, edges and small features can produce unstable or mixed readings. |
| Standard | Protect master and verify working copies | Handling damage and ageing can slowly move the reference itself. |
| Assembly | Include a controlled visual review | Instrument data controls color; the final review confirms harmony across different surfaces. |
One product may need more than one method
Use SCI for material-color control where surface variation should be reduced, SCE or a separate gloss check where finish matters, transmission for clear parts and controlled backing for translucent components. Link those methods with one final appearance standard.

Consumer Products color measurement FAQ
How do you match plastic and painted-metal components?
Approve the visual combination, then define a suitable method for each material. Their numeric Lab targets may not be identical even when the assembled appearance is acceptable.
What if the measurement area is smaller than the aperture?
Use a smaller verified aperture or a fixture that isolates the intended area. Never accept a reading that includes an edge, opening or adjacent color.
Should every supplier use the same instrument model?
It helps, but the essential requirement is correlation: same geometry, settings, standard, presentation and demonstrated agreement across the expected color range.
Can one Delta E limit cover every product color?
Usually not. Visual sensitivity changes with color, finish, component adjacency and product expectations. Validate tolerances with representative boundary samples.
