What should I pay attention to in car paint color matching?

Matters needing attention in paint color matching are as follows: 1: paint color matching needs to be cautious. Generally, try the sample first, get the quantity of tinting paint first, and then prepare the sample according to the results of the sample. First, adjust the secondary color and secondary color in a small container. 2. First add the main color (the color with large dosage and low tinting power), then slowly add the dark color (or tinting) with high dyeing ability, and keep stirring to observe the color change at any time. 3. "From shallow to deep", especially adding pigments with strong coloring power, do not overdo it. 4. In color matching, the colors of paint and dry film will be slightly different. When all kinds of paints are dry, their colors will deepen. 5. It is necessary to know in advance the floating degree of primary colors and the changes of coating materials in colorful coatings, especially amino coatings and perchloroethylene coatings.
