When buying furniture, everyone will find that solid wood furniture will more or less show the phenomenon of color difference. So, does the color difference of furniture have anything to do with quality?

We all know that there will not be two identical leaves on a tree, let alone two different trees. Next, let's talk about what causes the color difference of solid wood furniture.

Factors that cause color difference

1. Natural attributes

For each tree, the difference in age and texture will also cause color difference, which is a problem of the natural properties of wood.

The chromatic aberration of solid wood furniture is mainly due to differences in tree species, origin, color, texture, etc. As long as the surface of solid wood furniture may have chromatic aberration.

2. The color difference of treetops and roots

If the solid wood furniture is made of tree root wood, the color will be darker than that of treetop wood. This is mainly due to the natural growth time of the tree. The root growth time is long, and the generated wood is thicker.

The tops of the trees just grow and the roots are not as thick as the roots, and will be lighter in color than the roots, but the color difference of the same color system will not be too different.

3. The color difference of bark and core

Cut a cross section of a tree, you can see that the woody sapwood and heartwood of the tree have a large color difference. This is mainly because the growth of the tree mainly depends on the sapwood to transport nutrients and water, which is prone to worms and decay.

But heartwood is different. Heartwood does not have living cells. Wood is harder than sapwood. Heartwood mainly plays a supporting role in trees.

4. Paint factors

The growth environment of each tree is different, and its structure will be different, with different colors and patterns.

When the wood is spliced ​​together and painted, there will be some color difference due to the degree of dilution of the wood, and different colors will appear, resulting in a slight color difference.

In addition, the paint of the product must be redistributed each time, and the number of paint layers is different, and the color will also cause slight differences.

5. Processing method

The opening method of solid wood furniture is different, some are made by diameter cutting, and some are made by string cutting. After processing, the texture is inconsistent, and the two cabinet doors with different wood grains will inevitably appear color difference.

 

 

6. Installation factors

When assembling solid wood furniture, the installer will try to assemble it so that the color difference will not differ too much, and try to look at the overall color of the furniture to be uniform and beautiful.

If there is a large deviation in the color of the furniture, if the material is okay, the installation master has not installed it properly.

7. Environmental factors

Generally, the color of solid wood furniture near windows is brighter than the color of cabinet doors in dark locations. This visual aberration of solid wood furniture is mainly affected by sunlight.

Different angles (front and side), different environments (light intensity), different devices (mobile phones or SLRs), and different pictures taken at different times (morning, mid, and evening) will cause visual chromatic aberration.

to sum up:

Real solid wood furniture products have color difference, which is often an effective way to identify the authenticity of solid wood furniture materials.

When buying solid wood furniture, you must accept the difference in color or texture! The original flavor is the best.

Through the color repair process, the color difference problem can be reduced. But it cannot be exactly the same.

Method to eliminate chromatic aberration

1. Surface bleaching

Surface bleaching is a chemical method to quickly eliminate the color difference of the substrate, but not all substrates are suitable.

Only light-colored substrates, such as pine, aspen, maple, etc., or the substrate has a darker color and the target color of the furniture is lighter, can be bleached to make the overall color of the substrate lighter and consistent .

2. Substrate adjustment

The substrate adjustment adopts green water (equalizer) or red water (white edge paint) to adjust the chromatic aberration, which is suitable for most materials, and can greatly reduce the chromatic aberration and achieve uniform color.

If the target color of the furniture is similar to the color of the dark part of the substrate, red water can be sprayed on the light part of the substrate to transform the light part into the dark part.

If the target color of the furniture is similar to the light-colored part of the base material, green water is usually sprayed on the dark part to reduce the red chromaticity and make the base material color closer.
