Qingyuan Automotive Repair Paint Manufacturer Tells You Five Essential Conditions for Automotive Color Mixing Technicians

2020-10-10 601

1. Having a certain foundation in art knowledge; Theory of three primary colors, hue, saturation, brightness, and specific illumination

In high school physics classes, we may have done experiments with prisms, where white light passes through the prism and is gradually transformed into a color spectrum of multiple colors, which are red, orange, yellow, green, green, blue, and purple in sequence. This is the visible spectrum. Among them, the human eye is sensitive to red, green, and blue, and the human eye is like a system of three color receivers. Most colors can occur through the composition of red, green, and blue according to different proportions. The vast majority of monochromatic light can also form three colors: red, green, and blue. This is the fundamental principle of chromaticity, namely the principle of three primary colors. The three primary colors are independent of each other, and no primary color can be composed of the other two colors. Red, green, and blue are the three primary colors that make up a wide range of colors. The three primary colors of red, green, and blue are added in different proportions to form a mixed color, which is called additive mixing.

The three attributes of color include: (1) hue, also known as color, is the fundamental characteristic of color and reflects its fundamental appearance. For example, red, blue, gray, purple, and so on. It emphasizes the most essential characteristics of the color of the sedan itself. It can be said that the color scheme of a car is what it is; (2) Saturation, also known as purity, refers to the purity of a color. As we all know, when colors are mixed in more than three different ways, a feeling of turbidity will occur. The more intense the color mixture is compared to illumination, the more pronounced it becomes. This is something that every colorist should pay attention to. For the first time learning how to mix colors with paint, it's okay to buy a box of gouache paint and practice on your own. You can also find someone to help guide you, and your progress will be faster; (3) Brightness, also known as brightness, represents the depth of colors. Brightness is easier to understand, which is the degree of brightness and brilliance relative to a certain color.

Let's talk about the fundamental type of color comparison: when two or more colors are combined, the color comparison effect formed by different colors is called color comparison. It is a fundamental aspect of color comparison, and the strength of the comparison depends on the spacing (viewpoint) between the color phases on the hue ring. The smaller the spacing (viewpoint), the weaker the comparison, and vice versa, the stronger the comparison.

Zero degree comparison

(1) Although colorless, their combination is very valuable in terms of usefulness. Such as black and white, black and gray, medium gray and light gray, or black and white and gray, black and dark gray and light gray, etc. Compared to the effect, it feels generous, serious, and elegant with a sense of modernity, but it is also prone to a monotonous feeling that is too simple. (2) There is no comparison of colors with colors such as black and red, gray and purple, or black and white and yellow, white and gray and blue. The contrast effect feels both generous and vivid. When there are no colorful areas, it tends to be elegant and serious, and when there are colorful areas, it enhances the sense of vitality. (3) The comparison of different brightness or purity changes of a color, commonly known as a combination of colors of the same kind. Compare colors such as blue with light blue (blue+white), green with pink green (green+white) and dark green (green+black). The comparison effect is consistent, quiet, elegant, implicit, and steady, but it is also prone to monotonous and rigid drawbacks. (4) Compared with similar colors such as white and dark blue, light blue, black and orange, and coffee, the colorful effect combines the advantages of (2) and (3) types. The feeling is both layered and elegant, vivid, and stable.

Harmonic comparison

(1) Nearby colors are compared to adjacent two to three colors on the hue ring, with a hue interval of about 30 degrees, indicating a weak contrast type. For example, comparing red and orange with yellow and orange. The effect feels soft, harmonious, elegant, and quiet, but it also feels monotonous, blurry, dull, and powerless, requiring poor brightness adjustment. (2) Similar colors have a contrast interval of about 60 degrees, indicating weaker contrast types, such as red and yellow orange contrast. The effect is rich and vivid, but without losing a sense of consistency, elegance, and harmony. (3) Moderate color contrast: The contrast interval is about 90 degrees, which is a type of medium contrast, such as yellow and green contrast. The effect is bright, vivid, full, and exciting, making people feel interested. The contrast has appropriate intensity but does not lose harmony.

Intense comparison

(1) Compared to the contrast color, the contrast interval is about 120 degrees, indicating a strong contrast type, such as yellow green and red purple contrast. The effect is intense, eye-catching, powerful, vivid, and rich, but it is not easy to be consistent, causing confusion, impact, and visual fatigue. Generally, multiple harmonic techniques are needed to improve the comparison effect. (2) Complementary color comparison: The color comparison interval is 180 degrees, which is the comparison type, such as red and blue-green, yellow and blue-purple comparison, etc. Intense and uncoordinated effects and other negative feelings.

With these fundamental color knowledge, it will have a certain assistance effect on learning car paint color matching. We also need to go through a lot of practice to experience, feel, and investigate why paint is this color, and why we need to plan colors in this way. Everyone knows. The colors of cars nowadays have become fashionable. Regarding anti color planning; Color stability; Fashion and popular color planning; We will discuss metal color planning and colorful planning in the future.

2. Having a certain basic knowledge of paint; Classification and differentiation of solid color paint, metallic paint, and pearl mica paint.

Solid color paint, also known as plain color paint, is a colored paint with concealment power (white and various color mixing paints). The concealment power in solid color paint is not different from inorganic pigments, such as titanium white, benzidine yellow, phthalocyanine blue, Yonggu red, Lisol red, carbon black, and so on. It is composed of resin, pigments and fillers, additives, and solvents. In addition, there are certain ingredients such as leveling agents, defoamers, and UV resistance. Different paints have different functions and effects due to their different resin compositions. Like car repair paint, it is composed of acrylic acid polyurethane, so it is also called acrylic acid polyurethane coating. It's just that the quality used on cars is better. The paint mainly consists of four parts:

Resin, perhaps called film-forming substance: - is the foundation of paint, which plays a decisive role in the performance of paint and film. It has the function of bonding other components of the paint to form the paint film. There are many types of substances that can be used as film-forming substances, but in modern times, they are widely used to form resins, such as alkyd resin, acrylic resin, chlorinated rubber resin, epoxy resin, etc.

Pigments - are a major component of colored coatings (lacquers). Pigments give color to the paint film, giving it the ability to conceal the object being painted, in order to achieve its decoration and maintenance effects. According to the effects in the paint guess, it can be divided into coloring pigments, physical pigments, and special pigments. Inorganic pigments are commonly used in lacquer guessing, and their composition is also widely used. Currently, pigments are developing rapidly.

Solvent - A substance that can dissolve or disperse the film-forming substance in the paint into a uniform liquid state for easy construction and film formation. After construction, it can also evaporate from the paint film to the atmosphere. In principle, solvents do not form a coating film and should not remain in the paint film. Some solvents are used during paint manufacturing, while others are used during paint construction.

Additives - also known as auxiliary material components of paint, but they cannot independently form a paint film. They can exist as a component of the paint film after the paint film is formed. The effect of additives is to improve the performance of a specific aspect of the paint or film. A paint guess can use multiple different additives to achieve different effects. (For example, defoamers, wetting agents, anti sagging, anti settling, drying agents, plasticizers, mold inhibitors, etc.)
