1. Find out the root of the problem.
First of all, we must find out the source of color difference. If only one corner or one wall is different in color from other parts, it may be just a matter of drawing or lighting. If the color difference is obvious, you can try to check the previous construction records to determine the cause of the problem.
Step 2: Color harmony
One solution is color harmony. In this way, the color of pigment can be adjusted by adding color. It may take some time to find the right mixing proportion, but when you find the right proportion, you will get a brand-new unified color.
Repaint
Another option is to repaint the surface to ensure that the same color is used. You can do this yourself or hire professionals to do it. However, it may take some time and money.
Use decorations
Finally, you can use decorations to hide the problems of different colors. Use wallpaper, wall stickers or some works of art to cover up the surface problems, so as to obtain beautiful effects.
In short, the problem of different colors of wall paintings is not unsolvable, although it is cumbersome. Proper communication and judgment are the key. Determine the root of the problem, choose the appropriate solution, and then carefully operate, you can get the ideal effect.
