Try to match the sample.
First of all, you need to determine how many colors of multicolor paint are contained in the paint sample or sample. Then, estimate the weight of all kinds of paints involved in color matching as the basis for preparing details. For the convenience of weighing, you can put the paints to be mixed into containers separately, weigh their gross weight before color matching, and weigh them again after color matching. The difference between the two weights is the weight of various paints.
Color matching skill
First, add the main color paint (large amount, little influence on color), then add the auxiliary color paint with strong coloring power, and keep stirring. In order to ensure a satisfactory color, you should always observe the sample or sample and stir it patiently. If beige paint is prepared, the white paint should be poured into the container first, and then the yellow paint should be gradually added and stirred to the satisfaction.
Pay attention to chromatic aberration
Paint becomes shallow when it is wet and becomes deep when it is dry. Therefore, the color difference between wet paint and dry paint, the floating degree of colored paint in multi-color paint and the change of paint materials should be considered when matching colors.
Add auxiliary materials
Auxiliary materials such as catalyst, curing agent, varnish and diluent may be needed when matching colors. Please note that if drier is needed, it should be added before blending, otherwise it will affect the color tone.
Main color matching
In color matching, we should be good at using color matching skills. For example, when paired with positive green, the yellow of the green head can be matched with the blue of the yellow head; When purple and red are matched, red-headed blue and blue-headed red are mixed. In this way, a purer color can be obtained.
Add white or black to adjust the depth.
In color matching, we can dilute the primary color or composite color by adding different components of white to get different shades of color. Similarly, adding black can adjust the brightness of the color.
Application of metal flash color
In foreign coatings and painting industries, metallic flash color is widely used in automobile, electrical appliances and other industries. This color can shine brightly in the sun, and is usually made by adding aluminum powder, copper powder or pearlescent pigment.
