New wood furniture does not stay the color it arrives. Within a year it will have shifted noticeably, and within ten it may be a different color entirely.
This is worth knowing before you buy, because the change is not the same in every species and it is not reversible. Choosing timber on the sample color alone is choosing on a temporary state.
What causes the change
Two processes, working at different speeds.
UV light breaks down the compounds that give timber its color. This is fast, most of the change happens in the first six to twelve months, and it is almost entirely driven by daylight, not by direct sun alone.
Oxidation is slower and continues for decades. Tannins and extractives in the wood react with air, generally deepening and warming the color.
The finish contributes too. Oil finishes amber slightly over years, warming everything under them. Water-based finishes stay clearer and let the timber's own change dominate.
Walnut: darkens, then lightens
The species that surprises people most, because it goes the opposite way to expectation.
American black walnut arrives with purple and gray-brown tones. Over the first year those cool tones fade and the wood lightens toward a warmer honey-brown. Over a decade it settles into a rich mid-brown with far less of the chocolate depth it had when new.
Steam-dried walnut, which is most commercial walnut, has had the sapwood darkened to match the heartwood. That darkening is less stable than natural color and fades faster.
If you want walnut to stay dark, keep it out of strong daylight. If you love the lighter, warmer aged walnut, put it somewhere bright and let it happen.
Cherry: the most dramatic, and the best
Cherry arrives pale pinkish-tan and looks, frankly, a little disappointing. Within six months it has deepened to a warm reddish-brown, and over ten years it becomes a deep lustrous red-brown that cannot be replicated with stain.
This is the classic case for patience, and it is also the strongest argument for even exposure. A cherry table with a placemat left on it for the first six months will carry the ghost of that placemat for years.
Speed it up deliberately if you want: put a new cherry piece in daylight, uncovered, and rotate anything that sits on it weekly for the first few months.
White oak: ambers slowly and steadily
White oak starts pale beige-brown with a slight greenish cast. It warms gradually to a golden amber over several years, the most predictable and gentle change of the common hardwoods.
It is a good choice for anyone who wants a light interior to stay light. It never goes dark on its own.
Red oak, by contrast, has a pink undertone that becomes more obvious with age, which is why it dates a room more visibly than white oak does.
Fumed or ammonia-treated oak is a different matter, that is a chemical reaction with the tannins, done deliberately, and it is stable.
Maple: yellows
Hard maple starts almost white with a creamy tone and goes progressively more golden-yellow. The change is modest for the first year and then continues steadily.
Maple is the species where uneven exposure shows most, because the starting point is so pale. A maple desk with a monitor stand on it will show the outline clearly within a year.
Acacia: darkens and evens out
Acacia arrives with dramatic contrast between pale sapwood and dark heartwood. Over time the pale areas darken faster than the dark ones, so the overall contrast reduces and the piece becomes more uniformly mid-brown.
People who buy acacia for the contrast should know it softens. People who find new acacia too busy should know it calms down.
Teak and oily tropical species: gray if exposed
Indoors, teak darkens gently to a warm brown. Outdoors and unfinished, it weathers to the familiar silver-gray within a year or two. The gray is a surface layer only, is not decay, and sands off if you want the brown back.
How to let it age evenly
- Rotate anything that sits on the surface. Lamps, trays, plants, runners. Weekly for the first six months, then occasionally.
- Turn pieces around if only one side faces a window. A table can be rotated end for end twice a year.
- Use sheer blinds rather than blocking light entirely. Slower even exposure beats sharp contrast between covered and uncovered.
- Do not cover a new piece with a cloth for its first year, which people do to protect it and which guarantees a two-tone finish later.
Wear, which is different from color
Color change happens to the whole surface. Wear happens where hands and objects go: the front edge of a desk, the arms of a chair, the center of a tabletop.
On an oiled finish this shows as a gradual loss of sheen in the used areas, and the fix is to re-oil, ten minutes, blends in completely. On a lacquered finish the same wear eventually goes through the film, and at that point the only fix is stripping and refinishing the entire surface.
This is the practical, unromantic argument for oil finishes on anything you actually use.
Matching new to old
If you are adding a piece to an existing set, buy the same species and accept that it will be noticeably lighter for the first year or two. It catches up. A stained match will not, stain fades on a different curve to natural color and the two diverge over time.
Where possible, let the new piece sit in good light for a few months before placing it next to the old one. It closes most of the gap.
Rootelier pieces are solid wood. In a solid board, what you see at ten years is the wood itself rather than a thick surface coating. See the range, or read the wood species guide if you are choosing between them.
