Why does solid wood furniture definitely have color differences?

There is a consensus among consumers that true solid wood furniture products have color differences, which are often an effective way to identify the authenticity of solid wood furniture materials.

If solid wood furniture eliminates color difference, it will affect the texture, visual integrity, and texture rigidity in the sensory sense. Is it necessary for solid wood furniture to have color difference?

Indeed, it is difficult for solid wood products to achieve complete color difference, as long as the color difference is controlled within an acceptable range, there is no problem. But what is the reason for the color difference to be reasonable, and what is the reason for the color difference to be unreasonable?

We cannot let consumers assume that all color differences are reasonable, which is definitely not conducive to improving the quality of our solid wood furniture.




1. Reasonable reasons for color difference:

Firstly, let's take a look at the reasonable reasons for the color difference in solid wood furniture. The so-called "rationality" refers to the uncontrollable reason why color difference cannot be changed through subsequent technical control.

The so-called color difference simply refers to the difference in color. For solid wood products, the reasonable reasons for color differences are mainly caused by the nature of the wood itself, wood cutting methods, and environmental factors.

The leaves on a tree cannot be the same, let alone two different trees. Even if using the same tree, the color near the center and root of the tree will be darker, while the color near the top and bark will be lighter.

Moreover, each tree, with different ages and textures, can also lead to color differences, which are natural properties of wood.




2. Color difference between tree tops and roots:

We all know that the colors of different parts of trees vary, and the first thing to talk about is the color difference between the roots and tops of trees.

As the main part of trees that absorb nutrients, the roots of trees have more pigment deposition, resulting in darker colors. However, taller tree tops have less pigment deposition and lighter natural colors.

As shown in the above figure, we can clearly see that the thicker part, near the root of the tree, is darker in color; The thinner part, close to the tree top, has a lighter color; The color depth in the middle of the thickness is between the two.

Sapwood refers to the part near the bark that has the function of transporting and storing nutrients. It is characterized by a lighter color, more moisture, and is prone to moths and decay. It is the part of the log with poor material quality.

Heartwood is the central part of a tree that no longer contains living cells, and its storage material (such as starch) is no longer present or converted into heartwood material. Usually dark in color, without the function of transporting sap and storing nutrients, it mainly supports the entire plant.




3. The color difference caused by different processing methods of logs:

The processing methods of logs vary, resulting in different surface textures. Usually, after cutting, three types of planes can be obtained, namely transverse plane, radial plane, and chord plane.

Cross section refers to the section perpendicular to the main axis of the tree trunk, which is the end face of the tree trunk. It can be used to observe the cross sections of various axial molecules and the width of wood rays. It is the most important section for identifying wood.

The radial plane refers to the longitudinal plane perpendicular to the annual ring through the pith center along the axis of the tree trunk. On a transverse plane, any longitudinal plane parallel to the wood rays is called a radial plane, and the wood rays on this plane are discontinuous and perpendicular to the annual rings.

The chord section is a section that follows the grain of the wood, does not pass through the pith, but is tangent to the annual ring. The wood rays in this section appear in a fine line or spindle shape, with V-rings forming patterns.

During the production process, the board with an angle between 45 to 90 degrees between the concentric tangent lines of the board surface and the tree trunk is called a radial cutting board, and the board with an angle between 0 to 45 degrees is called a chord cutting board.

Nowadays, many large brand solid wood furniture companies control color differences in their production processes, but rarely use chemical methods to completely eliminate color differences, because doing so deviates from the essence of solid wood furniture. Solid wood furniture is healthy and environmentally friendly, and choosing the right brand is crucial.


The wooden products produced by our company, such as Plywood, cater to the global environmental characteristics, so there may also be a slight color difference.
