At a glance
| Type | What it is | Light and matching | Where it suits |
|---|---|---|---|
| Natural veneer, finished | Sliced leaf of one species | Colour changes with light and age; the change is normal and varies by species (general knowledge, not tested here) | Match to a sample; do not expect it to stay put |
| Dyed natural veneer | Real leaves of one species, colour changed by dye | Each leaf keeps its own figure, so matching is by leaf; fastness depends on dye and process, ask for data | Colours not found in nature; accept leaf variation |
| Reconstituted (multilaminar) veneer | Dyed leaves laminated into a block and re-sliced | Engineered to repeat, but the colour still depends on the dye lot | Large or repeated runs |
| Stained or toned on the surface | Colour applied to the face or in the finish | Wear or sanding can show pale timber; fastness is a finish question | Cheaper colour change; check wear and repair |
Fastness figures for dyed veneer are not published in any source we found. Ask for the supplier's test result, its method and the exposure.
Dyed natural and reconstituted veneer
Dyed natural veneer is a real sliced leaf of one species whose colour has been changed by dye. Every leaf keeps its figure, so colour and pattern differ leaf to leaf. Reconstituted (multilaminar) veneer is made from dyed leaves laminated into a block and re-sliced, so both colour and grain can be designed and repeated. Both can look consistent on a sample card and still vary between dye lots. Our veneer specification sheet covers species, cut, leaf and panel matching, which apply here unchanged.
How far the dye goes into the leaf is the supplier’s information. A leaf dyed through its thickness keeps its colour if lightly sanded; colour near the surface only may show pale timber. Ask which, and do not assume.
Light exposure and lightfastness
All coloured materials change in light, and the amount depends on the dye, the wood, the finish and the exposure: direct sun through a window is a harder test than a dim corridor. We found no published fading data and no standard for the lightfastness of dyed veneer. The nearest widely used method is the textile test ISO 105-B02, which exposes a specimen under a xenon arc beside blue wool references numbered 1 to 8, each step needing roughly twice the exposure of the last (from public previews read on 5 November 2026; the current edition is shown as 2014 in catalogue summaries). It was written for textiles, so a result for veneer would be an adapted use, which the supplier must declare.
What to ask: the method, the exposure, the grade reached on the blue wool scale or equivalent, and the finish that was on the specimen. A result for the bare dyed leaf does not cover a lacquered panel, and a UV-filtering finish changes the picture. Treat any claim of ‘lightfast’ without a method and a grade as unproven. Plan for placement: avoid a dyed panel facing a south window, or specify blinds or glazing with UV control, and tell the client that all colours change in time.
Matching across leaves, panels and lots
Matching has three levels. Within a panel, leaves are matched as set out on the veneer sheet. Between panels, say whether adjacent panels must read as one run. Between lots, which is where dyed veneer is most exposed, a later order may differ from an earlier one even when the colour code is the same. We found no published tolerance for colour match between dye lots, so write a rule, not a number.
The routine: order the whole job, plus a reserve for repairs and changes, from one lot where you can; keep a signed leaf from each lot as the reference; check every lot against that sample in the room’s own light before pressing; and keep reserve veneer from the same lot for future repairs (see spares and attic stock). Finish samples must be made on the same veneer, because the finish changes the colour (finishes on timber joinery). The approval sequence is in sample hierarchy and approval.
Finish, movement and care
Dyed veneer moves with humidity like other veneer and needs balanced construction: see timber movement in panelling and veneer. Cleaning: use only the method in the finish supplier’s data; solvents and abrasive pads can lift colour or a surface coat. A repair on a dyed leaf is a colour-matching task, so record the lot and the finish in the handover pack (handover and O&M pack).
Make Bespoke Studio coordinates manufacture through partner workshops; which dyed or reconstituted veneers a partner can supply, and what data the supplier holds, is confirmed project by project and is not stated here.
Specification wording
Paste into your schedule or specification and replace anything in [square brackets] with your own figures. Wording is a starting point: your specification governs.
Veneer [item ref]: [dyed natural veneer of species / reconstituted (multilaminar) veneer], colour [supplier code and name], cut [ ], leaf match [book / slip], supplier lot [ ], as per signed sample [ref]. Dye penetration [through the leaf / near the surface], stated by the supplier in writing.
[Supplier] provides, before approval, a lightfastness result for the finished specimen: method [ISO 105-B02 or equivalent, adapted use declared], exposure [ ], grade reached [ ] on the [blue wool scale / grey scale], finish on the specimen [ ]. Claims of lightfastness without method and grade are not accepted.
All veneer for [areas] is supplied from one lot [number], plus [ ] per cent reserve from the same lot held for repairs. A signed leaf from each lot is kept as the reference. Any later lot is approved against it in the room's own light before pressing. Colour is not guaranteed to match across lots; the rule applies, not a numerical tolerance.
Sample finish is made on the same veneer, with the finish system [ ]. Location [orientation, glazing, blinds]; exposure to direct sun [yes / no]. Client is told that all colours change in time, and the change is not a defect. Cleaning to the finish supplier's data only.
Terms used on this page
- Dye lot
- A batch of material dyed together; a later batch may not match even when the colour code is the same.
- Lightfastness
- How well a colour resists change when exposed to light. For textiles it is rated against blue wool references 1 to 8.
- Blue wool scale
- Eight dyed wool references, each fading at a known rate, roughly twice as slowly as the one before, used to rate light exposure.
- Multilaminar (reconstituted) veneer
- Veneer made by laminating dyed leaves into a block and re-slicing it, so colour and grain can be designed and repeated.
- Dye penetration
- How far the colour goes into the thickness of the leaf.
Standards and sources
- ISO 105-B02 (textiles, light fastness, xenon arc): public preview read 5 Nov 2026; catalogue summaries show the 2014 edition as current. A textile method: use for veneer is an adaptation. Confirm on BSI Knowledge.
- No standard found: We found no standard for lightfastness of dyed veneer, no published fading data and no tolerance for colour match between dye lots.
Questions we are asked
Will dyed veneer fade?
All coloured materials change in light. How much depends on the dye, the species, the finish and the exposure. Ask the supplier for a result with the method, the exposure and the finish, and avoid strong direct sun on dyed panels.
Is there a standard for lightfastness of veneer?
We found none. The textile method ISO 105-B02 is sometimes adapted. The supplier must say what was done.
Can I get a second order to match the first?
Not guaranteed. Dye lots can differ. Order the whole job and a reserve from one lot where possible, and approve any later lot against a signed sample.
Is reconstituted veneer more consistent than dyed natural veneer?
It is designed to repeat, but the colour still depends on the dye lot. Ask for the lot number and a sample.
What if the dye shows pale timber when sanded?
That suggests the colour is near the surface. Ask the supplier how far the dye goes into the leaf before choosing.
