Which car color shows the least noticeable paint touch-up color difference?

[McFelix]

Black cars show the least noticeable paint touch-up color difference. Here are the relevant explanations: 1. Most prone to color difference: Non-metallic pure white car paint is most likely to show color differences during later touch-ups. This is because white is the base color among all colors, and current vehicle white paints are not pure white but are formulated by adding other color paints to the white base. Additionally, the human eye is most sensitive to color differences in white. Even slight variations in paint mixing can result in very noticeable color differences when sprayed on the car body. 2. Definition of car paint scratch repair: This refers to the repair of shallow scratches, stains, and oxidation on the car's paint surface caused by external environmental factors, as well as deep scratches that expose the primer due to human-induced scrapes.
