Understanding Wood Grain and Colour Variations

One of our top customer service inquiries revolves around concerns about unappealing wood grain or colour variations.

"This grain does not look like the one in the product photos."

"Why do the two chairs I bought have different wood tones?"

"Can I exchange this piece for a better-looking one?"

From minor cosmetic preferences to doubts about the material quality, these conversations happen often. In reality, these details are simply the natural characteristics of real wood.

Natural wood is never flawless. Markings, knots, mineral lines, unusual grain patterns, and localized color variations are all natural signs of growth. Because of this, every single piece of furniture is a unique and limited edition as it is.

Many people choose solid wood furniture because they want that untouched, natural texture. However, when the product arrives, we sometimes find that our actual tolerance for natural is lower than we expected. Taking a little time to understand how wood grows can give you a completely new perspective.

What is Wood Grain?

Wood is one of our oldest building materials. It is deeply familiar, yet it remains a complex and variable material because trees are incredibly diverse. A tree's roots expand in the wilderness for decades or centuries. It cannot grow without leaving a record of its life, especially after surviving extreme weather and insects.

The grain patterns on a wood surface are directly related to the internal cell movement of the tree. From a technical standpoint, wood grain refers to the alignment and direction of the longitudinal wood cell fibers. As a tree grows, these fiber bundles align with the axis of the trunk, branches, or roots, creating distinct lines.

Specific growing environments also create unique markings. For example, dark mineral lines occur when a tree absorbs minerals like carbonates from the soil. These deposits leave permanent tracks that vary naturally in depth and colour.

Aside from natural growth patterns, the way a log is cut also changes how the grain looks.

Carpenters understand how to work with wood grain better than most furniture buyers. For a smooth cut, the golden rule is to go with the grain. Think of it like petting an animal: brushing down with the fur feels entirely different from brushing backwards against it. Wood behaves the same way. Different wood types and cutting methods suit different designs.

Aside from solid wood, we love solid wood multilayer boards. Compared to solid wood furniture, which requires harvesting more trees, multilayer boards maximize wood utility. This makes them a lower carbon choice with superior stability. Initially, we sourced imported E0 grade multilayer boards. To improve quality further, we began selecting premium solid wood logs to press our own boards. Even with strict quality control at the source, and even with our selection of exceptional wood for engineering, natural traits like dark knots are still inevitable.

Why is There Colour Variation?

No two leaves are identical, and the same rule applies to trees. Even wood taken from the same trunk will show colour differences. Generally, wood closer to the root and the center of the tree (heartwood) is darker. Wood closer to the bark and the upper branches (sapwood) is lighter.

Even within a single growth ring, colours fluctuate between springwood and summerwood. Spring brings plentiful rain and optimal temperatures, producing softer wood with a lighter colour. Summer and autumn bring less rain and shifting temperatures, resulting in harder, darker wood layers.

Natural laws dictate that furniture made from different parts of a tree will look different. For our Tree Clothes System, we use solid ash wood. Ash features a dark core that lightens significantly toward the edges. To achieve a clean look, we use the lighter wood from the outer edges for the rack branches.

Aside from natural variations within a single piece of wood, batch differences during production are common and harder to avoid. This is especially true for furniture assembled from multiple wooden parts. We always try to match similar colours and grains during assembly, but we cannot guarantee an exact match.

How to Appreciate Wood Grain and Colour Variation

The beauty of natural wood lies in its origin. When making furniture, we prefer to preserve the raw texture of the wood as long as it does not impact structural quality. This means colour variations and grain differences are unavoidable.

A natural variation might feel unpredictable, like opening a blind box. Modern manufacturing constantly evolves to meet consumer demands for uniformity through techniques like opaque painting or veneering. These methods hide natural variations, but they create a completely different style of aesthetic.

Even with veneering, a minor level of colour variation remains. When we encounter raw components with larger visual irregularities, we send them to be painted. You might notice that our colored options are sometimes priced lower than the natural wood finish. This is our way of adjusting for those natural variations.

A tree is its own small universe. It has incredible expression through unique grains, diverse knots, and deep colour tones. If we only value perfectly uniform, knot-free straight lines, we miss out on the true personality of nature. We also fail to maximize the gifts of our forests.

Try to view wood the way a carpenter does. Do not fight against the grain. Instead, try to understand its story. You might start to see that the lines on a chair look like rolling mountains, the patterns on a post resemble rippling water, and the surface of a table looks like natural marble.
