When you re new to color, who knows what basic concepts you should know first?

First of all, the most basic understanding of color blending is the use of three primary colors

And then the cool and warm tones are easy to understand, and to put it simply, the blue is cool, and the yellow, red, is warm.

To understand this, you also need to understand the complementary color, the intercolor, which is the best comparison color wheel, and the two colors that are opposite each other at 180 degrees on the color wheel are complementary colors.

For example, magenta, green, purple and yellow, blue and orange, etc., it is best to understand the tone of the color, high-key, middle-key, low-key, etc., I won't go into details, you have an understanding, and you will understand it later.

First understand the names of various colors, then understand what hue is, then purity, then saturation, cold and warm. It is recommended to start with gouache, because gouache has a strong covering ability, and it is necessary to grasp the amount of moisture when the colors are connected, as well as the chemical reaction produced after the various colors are blended, and the color effect after the colors have dried. Once you've mastered all of this, it's time to start pulling the space and shaping the body.

First of all, you need to know the 3 primary colors, and then you must be able to skillfully tune out the colors, if you are warm and cold, the red and yellow ones are warm tones, and the blue and green ones are cold, it depends on personal feelings, just pay more attention to the surrounding colors. There is also the ambient color, which is indispensable. Reflectivity must be there, otherwise the sense of space will not be strong.

Then it's a matter of following your feelings.

Color is a visual effect on light produced by the eyes, brain, and our life experiences. A person's perception of color is not only determined by the physical properties of light, for example, the human perception of color is often affected by the colors around it. Sometimes people also refer to the physical properties of matter producing different colors directly as colors.

The wavelength and intensity of electromagnetic waves can vary greatly, and in the range of wavelengths that a person can feel, it is called visible light, and sometimes it is also referred to simply as light. If we list the intensities of the wavelengths of a light source together, we can get the spectrum of that light source. The spectrum of an object determines the optical properties of the object, including its color.

Different spectra can be received by humans as the same color.

1. Color of same kind: color of same kind refers to the same hue nature, but the chroma is different. (the color within the 15° angle of the hue ring), such as dark red and light red.

2. Adjacent color: The so-called adjacent color is the color that is adjacent to each other on the color band, such as green and blue, red and yellow are adjacent to each other. Between the neighboring colors, you often have me, and I have you.

For example: vermilion and orange, vermilion is mainly red, with a slight amount of yellow in it; Orange is predominantly yellow with a hint of red in it, and although they differ greatly in hue, they are visually relatively close. In the color wheel, all colors within the 60-degree range belong to the range of adjacent colors.

3. Complementary color: Among the three primary colors, any one color is the complementary color of the other two primary colors mixed in equal amounts. In the hue ring, the two colors at the diameter position complement each other.

There are three primary colors, namely red, yellow, and blue, which are units of color that can no longer be broken down. The colors produced by the matching of each two groups of the three primary colors are called intermediate colors, such as red and yellow are orange, yellow and blue are green, blue and red are purple, and orange, green, and purple are called intermediate colors. Red and green, orange and blue, yellow and purple are complementary colors.

4. Contrasting color: The color opposite (180 degrees diagonal) of each color in the hue ring is called"Contrasting colors (complementary colors).".Putting contrasting colors together can give a strong sense of repulsion.

If mixed together, it will bring out a cloudy color. For example, red and green, blue and orange, yellow and purple are contrasting colors.

Contrasting colors can also be defined in this way: two colors that can be clearly distinguished, called contrasting colors. Including color contrast, brightness contrast, saturation contrast, cold and warm contrast, complementary color contrast, color and achromatic contrast, etc.

5. Similar colors: The colors that are adjacent to each other within a 90-degree angle on the color wheel are collectively called similar colors. For example, red, red, orange, orange.

Yellow, yellow, green, green. Blue, bruised, purple, etc. are all similar colors. Similar colors are often used in color matching because the color contrast is not strong, giving people a sense of color, calm and harmony.

A visual psychological sensation caused by the reflection of light from an object to the human eye. Color can be divided into color and color in the literal sense, and the so-called color refers to the feeling of light that enters the eye and transmits it to the brain; Color refers to the meaning of multiple colors, which is people's understanding of the changes in light.

1. Color is composed of three elements: intrinsic color, light source color, and environmental color.

Intrinsic color is the color that appears under the irradiation of sunlight, such as leaves are green, flowers are red, sky is blue, lemons are yellow, etc. The color of the light source is the color of the light source shining on a white smooth opaque object, such as a white shirt, which appears red under the irradiation of the red light source and blue when illuminated by the blue light source.

The ambient color is a reflection of the color of the environment in which the object is located. When an object is irradiated by a light source, in addition to being irradiated by the main luminaire (or reflector), it may also be affected by the secondary luminaire (or reflector), but the influence is weaker than the former, and the color of the secondary luminaire (mainly the reflector) is reflected on the dark side of the object, which is the ambient color.

Second, the three primary colors of color.

The three primary colors are composed of red, yellow, and blue, which are independent of each other, and any two colors will be composed of different colors. Such as red + yellow = purple, yellow + blue = green and other different colors. The three colors are the basis of painting, and only by understanding the nature and characteristics of the three primary colors can the true meaning of color be applied.

3. Color has three elements, which are composed of brightness, brightness, and saturation.

Brightness refers to how light or dark a color is. Various colored objects have a sense of light and dark due to the difference in the light they reflect. By properly processing the brightness of each part of the object, it is possible to create a three-dimensional sense of the object.

White is an important factor that affects lightness, and when brightness is insufficient, white is added and vice versa.

Light exists, color existsColor composition definition: the reconstruction of existing color elements. The definition of color composition in the field of art: the regular, thoughtful and aesthetic collocation of colors that need to be used in art and design.

The theoretical basis for the study of the composition of color: physics, chemistry, biology and psychology allow us to understand the nature of color, the visual laws of color, and the impact of color on human psychology.

The three elements of color: lightness, purity, and hue.

Color presentation system: In the field of fine arts or design, people usually use two main categories to represent the interrelationship of colors. One is the hue ring, the most basic is the color relationship between 12 colors and 224 colors, and the other is the three-dimensional display form of color.

Color can beautify people's spiritual world.

The three elements of color, hue, lightness, and purity.

Hue: The tendency of the color, just like the colors displayed by the rainbow, the red-orange is yellow-green and blue-violet.

Brightness: A color gradually whites and eventually becomes white, and gradually blackens and finally becomes black.

Purity: The purity is highest when there is no variegation in a color, such as pure red gradually decreases in purity and finally turns gray.

When using contrasting colors, it can make the other person stand out very clearly, and if you use equal color areas, it can be tiring to look at.

If a person's eyes look at a color for a long time, it will make the eyes tired, and the contrast of this color (complementary color) will be automatically generated, and the desire to see his contrasting color will be long, such as the doctor in the operating room will be tired when he looks at the red blood for a long time, and when his eyes are removed from the bloodstains, green blood will appear in front of his eyes, and all the doctors in the operating room wear gray-green clothes, mainly to relieve eye fatigue.

When it comes to design, color is extraordinarily attractive. Color brings people the first feeling of the ancestors of the design works, so as to obtain a distinct visual experience, which can induce the audience to further appreciate the design intention; In further service to the design, color can be combined with the modeling, strengthen the meaning of the shape and explain the information, enhance the expressiveness of the image, and bring out the unique emotional atmosphere. Therefore, color is an indispensable role for design to convey information and express emotions, and color is the unity of sensibility and rationality.

Color composition is based on the study of color, physical and chemical properties and the physiological and psychological experience it brings to people, and through a large number of systematic color training to improve our sense and sensitivity of color.
