Does repainting with a different color have any impact?

[SanMartin]

Repainting with a different color does have an impact, as the original paint needs to be sanded off. Reasons for color differences after car repainting: Primarily, it's due to the difference in paint material compared to the original car paint. The original car paint uses computer color matching, while touch-up paint no longer employs this method, placing high demands on the repair technicians. Even highly skilled technicians cannot achieve a perfect match with computer color matching. Additionally, wear and oxidation of the original paint over time can also lead to color differences. Reasons for treating the original paint: If the original paint is not removed, the repainted area will be higher than the surface of the original paint. When the new paint and old paint blend, they may separate and peel off, rendering the repainting effort useless.
