During decoration, customers often ask why the color on my wall after painting is different from the color I chose on the color card? Which is better, machine paint mixing or manual paint mixing? There are always various problems with color matching around wall paint like this.

1、 Why is there a color difference between the painted wall and the color card?

1、 Reason for coloring area

The biggest reason for this is that the area of the color card used for reference is usually very small. A color is only the size of a square, and it cannot fully reflect the overall effect of the wall after construction using that color. Therefore, the color presented on the entire wall may deviate from the color card, and the painted wall will generally be much lighter than the color card.

2、 Differences in light and angle

Affected by the environment, each color presents a different visual experience under different lighting and angles. Usually, a series or a certain process of color cards are fixed together. Due to the similar colors and various types, it is inevitable to misjudge after looking at them for a long time. Therefore, when encountering a color you like, it is best to extract it separately and observe the color changes under different lighting conditions to minimize errors.

3、 There is deviation in manual color matching

There are many factors that can cause color difference, whether it is computer color matching or manual color matching by construction workers, they cannot achieve 100% color consistency with the color card. All color cards and the final color presented after color matching will inevitably have deviations, as long as it is within a reasonable range, it is not a problem. Especially for some inexperienced craftsmen, poor control of the proportion during the color mixing process can also lead to color differences. It is recommended that owners supervise the wall decoration on site and communicate with construction personnel in a timely manner if there are any problems.

4、 Other factors

Sometimes when different models of mobile phones look at the same color, the results may also have deviations. For example, if the owner is unable to go to the scene to check the color card, they may entrust relatives, friends, or partners to take photos and send them to the owner for viewing. Due to the different resolutions of their phones, there may be a deviation between the color difference and the desired color displayed by the two people's phones. If you are worried about the large color difference on the wall, you can adjust the color and test the color locally in inconspicuous areas on the wall. Let the color matching master gradually adjust from light to deep until the color is satisfactory.
