1. Having a certain basic knowledge of art; Theory of three primary colors, hue, saturation, brightness, and contrast

In high school physics classes, we may have experimented with prisms, where white light passes through the prism and is transformed into a color spectrum of multiple colors that gradually transition. The colors are red, orange, yellow, green, green, blue, and purple, which is the visible spectrum. Among them, the human eye is like a system of three color receivers for red, green, and human eyes. Most colors can be generated through the composition of red, green, and blue in 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 addition of the three primary colors of red, green, and blue in different proportions to form a mixed color is called additive mixing.

The three characteristics of color include: (1) hue, also known as color, which is the basic feature of color and reflects its basic appearance. For example, red, blue, gray, purple, and so on. It focuses on the essential characteristics of the color of the car itself. It can be said that the color of a car produces the same hue; (2) Saturation, also known as purity, refers to the purity of a color. We know that when three or more colors are mixed, there will be a feeling of turbidity, and the more intense the contrast of the color mixture, the more pronounced it will be. This is something that every colorist should pay attention to. For those who are new to learning paint color mixing, it's okay to buy a box of gouache paint and practice it on their own. They can also seek the help of a painter to teach them, and progress will be faster; (3) Brightness, also known as brightness, represents the depth of a color. Brightness is easier to understand, which is the degree of brightness and beauty relative to a certain color.

Let's talk about the basic types of color comparison photography: When two or more colors are combined, the color comparison effect formed due to color differences is called color comparison photography. It is a fundamental aspect of color contrast, and the degree of contrast depends on the distance (angle) between the hues on the hue ring. The smaller the distance (angle), the weaker the contrast, and vice versa, the stronger the contrast.

Zero degree contrast

(1) Although there is no color contrast, their combination is 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. The contrast effect feels generous, strict, and elegant, giving it a sense of modernity, but it can also create an overly simple and monotonous feeling. (2) There are no contrasting 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 large areas of colors, it tends to be elegant and strict, and when there are large areas of colors, it enhances the sense of vitality. (3) Comparison of similar colors refers to the comparison of changes in brightness or purity of a color, commonly known as a combination of similar colors. Contrast colors such as blue with light blue (blue+white), green with pink green (green+white) and dark green (green+black). The contrast effect is consistent, quiet, elegant, tactful, and cautious, but it can also have the drawbacks of monotony and rigidity. (4) Compared with similar colors such as white and dark blue with light blue, black and orange with coffee, the effect combines the advantages of (2) and (3) types. It feels both layered and generous, vivid, and stable.

Harmonious contrast

(1) Nearby colors are compared to adjacent two to three colors on the hue ring, with a hue distance of about 30 degrees, indicating a weak contrast type. Compare red and orange with yellow and orange. The effect feels soft, harmonious, elegant, and quiet, but it also feels monotonous, vague, dull, and powerless. It is necessary to adjust the brightness difference. (2) Similar color comparison: The color comparison distance is about 60 degrees, indicating a weaker contrast type, 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 distance is about 90 degrees, which is a type of medium contrast, such as yellow and green contrast. The effect is bright, vivid, full, and uplifting, and there is a feeling of preference. The contrast has appropriate strength, but it does not lose a sense of harmony.

Intense contrast

(1) Contrast color comparison: The contrast distance 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 and feels messy, influential, and forms visual fatigue. Generally, multiple harmonious techniques are required to compare the effects. (2) Complementary contrast colors are compared at a distance of 180 degrees and are point contrast types, such as red and blue-green, yellow and blue-purple contrast, etc. The effect is intense, uncoordinated, and other negative sensations.

With these basic color knowledge, it will have a certain assistance effect on learning car paint color matching. We also need to go through many practices to experience, feel, and investigate why paint is this color and why we plan colors in this way. We know. The colors of cars nowadays have become fashionable. Regarding color planning; Color stability; Fashion and popular color planning; Metal color planning and Huancai color planning
