Nacreous · Pearl
Nacreous ACP
Pearlescent coatings with a soft depth that changes with light rather than with angle.
Spectra · Colour Shift
Spectra ACP
Colour-shifting coatings that change character with viewing angle and light.
Product Overview
Spectra ACP At A Glance
Spectra coatings hold more than one colour at once. The pigment shifts as the viewing angle changes, so a facade reads gold from one approach and bronze-green from another, and a curved surface reads as a gradient.
It is a deliberate architectural effect: on a flat, evenly lit elevation the shift is subtle, but on curves, fins and angled bays it becomes the point of the design.
Key Benefits
Why Buyers Choose This Panel
01
Colour that changes with the approach
The elevation looks different from each side of the street.
02
Reads best on curves and angles
Fins, bays and curved bands amplify the shift.
03
Full composite panel behaviour
Fabricates and installs like any coated panel.
04
Available across coating systems
Including durable exterior systems for a permanent facade.
Application Scenarios
Where It Is Used
Signature facades and feature bays
Where the building has to be recognisable.
Curved bands, fins and canopies
Geometry that shows the shift.
Retail and entertainment exteriors
Attention as a design brief.
Interior features and display
Reception walls, bars, exhibition stands.
Who It Is For
- Architects on signature buildings
- Facade contractors quoting a special finish
- Retail and entertainment developers
- Exhibition and display builders
Problems It Solves
- An elevation that looks flatA colour-shift finish gives a plain surface depth without adding geometry.
- Matching a shifting colour laterTell us at the first order so the batch reference is kept for later phases.
- Uncertain how it will lookJudge it on a physical sample, angled, in daylight — a photograph cannot show a shift.

Manufacturing Process
Three Lines Under One Roof
Every panel passes the same three stages in our own factory, with batch records at each one.
01
Chemosynthesis Line
Coil cleaning and conversion coating before any paint is applied.

Precision Coating Line
Three-roller reversal coater in a sealed dustless environment.
03
Lamination Line
Metal, core and adhesive film bonded under heat and pressure.
04
Inspection And Packing
Appearance, coating, mechanical and weathering checks before nude or wooden-pallet packing.

Use Guide
How To Specify And Order
- Look at a physical sampleHold it at several angles in daylight before deciding.
- Use it where geometry helpsFlat, evenly lit walls under-sell the effect.
- Order the whole area at onceColour-shift finishes are the least forgiving of a second batch.
FAQ
Spectra ACP FAQ
Can spectra finishes be matched later?
Colour-shift systems are the hardest to match across separate runs. Order the full area together where possible, and tell us if a later phase is planned so we can hold the reference.
Is spectra suitable for exterior facades?
Yes, in a durable exterior coating system. Send the location and expected service life and we will confirm.
Can you develop a custom effect?
Our lab develops custom colours from a physical sample, typically producing a lab-dip within five days for approval.
