Brightness The difference and relationship between purity Who specifically and vividly says it

White brightness is the highest, the lighter the color, the higher the brightness, as long as more than one color is added to one color, then its purity will be lower.

To put it simply, the degree of clarity refers to the brightness and darkness of the object, and the purity is whether the object is pure or impure, and the amount of other colors or impurities it contains.

Shades categorized by lightness.

"Brightness" refers to how light or dark a color is. White has the highest brightness and black has the lowest. The brightness of different hues is also different, yellow has a high brightness, and red and blue have a low brightness.

Any kind of hue such as the addition of white, will increase the brightness, the more white components, the higher the brightness; If any hue is toned with black, the brightness is relatively reduced, and the more black, the more brightness.

Shades composed of white or brightness hues are called "high-key".

"High tone" is determined not only by the brightness of the hue that makes up it, but also by the intensity of the light. For example, the hue with low brightness will also increase under strong light. Conversely, in dim light, the high-brightness hue will also become darker.

At the same time, the brightness of objects is different at different light angles, such as high-brightness objects, which are still very low in the dark.

If, according to Munsell's three-dimensional theory of color, the difference in brightness from black to white is divided into nine color levels, then 1-3 is the low brightness color scale; 4-6 is the medium brightness color scale; 7-9 is the high-brightness color scale.

The hue of the color in the middle of the scale is called the midtone.

Shades classified by purity.

Purity refers to the degree of purity and saturation of a color. Colors of different hues, colors that are not mixed with other components, then, the hue, the color is pure.

The concept of purity of a color is relative and at the same time associated with the name of the color. If vermilion is the purest, if it is mixed with a certain amount of yellow, then vermilion is not pure, but it becomes the pure color of orange.

The intensity of color purity is due to the mixing of other variegated colors.

Purity is also known as chroma, which is compared to black and white. Black and white are colors and colorless.

Tones made up of different purities, which can be divided into fresh, middle and grey tones. However, since the color from solid color to gray is a fairly wide field, fresh tones can also be distinguished into strong fresh tones, medium fresh tones and weak fresh tones. Intermediate colors have more variations in purity.

Therefore, this classification can only be relative.

Between "fresh" and "gray" tones is "medium-purity tones". Colors of intermediate purity are a fairly broad field and can be said to vary endlessly.

The tones made up of intermediate colors are rich and beautiful, and many of the colors seem to be subtle, but they have a strong personality.

The "low purity" hue is also known as the "gray tone". Gray contains black elements, but gray should also have different hues and a tendency to be warm and cold. The gray color is well handled, and it looks calm and elegant.

Black mixed with white is neutral gray, and when mixed with red, it has a gray-purple tendency; When mixed with yellow, it tends to be gray-green, and it looks very calm.

Differences:

1. Brightness refers to the brightness of the color, and the brightness and darkness of the color due to the amount of light reflected by the color; Purity refers to the degree of purity of a color, which indicates the proportion of color components contained in a color.

2. The brightness must be expressed by the light source, the color appears bright under strong light, and the color appears gray and blurry under low light; Purity must be expressed with the help of the proportion of color components, which is directly proportional to the purity of the color.

Introduction: Color purity refers to the percentage of primary colors in a color. Purity is used to express the shades and shades of color.

Purity is the criterion for judging the vividness of colors such as dark and light colors. The purest color is the primary color, and as the purity decreases, the color fades. When the purity is minimized, it loses its hue and becomes colorless, i.e., black, white, and gray.

In the color system, chroma or saturation is often expressed, and the purity of black and white can be called grayscale.

Color brightness refers to the brightness of a color. There are shades, light and dark variations in color. For example, yellow colors such as dark yellow, medium yellow, light yellow, and lemon yellow are not the same in brightness, and red colors such as blood red, deep red, rose red, bright red, vermilion, and orange are also different in brightness.

The different changes in the light, shade, and shade of these colors are another important feature of the color.

Brightness, purity, and hue are the three elements of color. The so-called lightness is the degree of lightness and darkness of a color, and its other name is also called dark and light color, through this element, people can see the various layers of the color. The so-called hue refers to the appearance of the color, and it is also the main basis for people to distinguish which color it belongs to.

Purity refers to whether a color is pure and how pure it is. Three elements, one indispensable.

Hue Judgment:Through the expression of the appearance of a color, people can determine which color it belongs to. If it is difficult to judge the color mixture, you can also roughly determine which color system it belongs to.

Hue is the appearance of the color that people can see directly, and it is also the appearance that can be presented very easily. Even people who don't know how to paint, through the depiction of colored pens, can directly present colors with a certain hue, so that people can easily judge the meaning of the color, for example, green refers to plants, red refers to the sun, and so on.

Brightness copying refers to the light and dark attack of color.

Extent. Includes solid colors with bai white and black.

The chiaroscuro relationship of a single hue that reciprocates. Brightness has a strong independence from purity, and it can be expressed separately by the colorless relationship of black, white, and gray. Hue and purity, on the other hand, are different and must be revealed in a certain amount of light and shade.

Brightness is the bone of color and the key to color.

Purity is called saturation or freshness, which refers to the degree of brightness of color and the degree of color content. Like red, when he mixes in with gray, it turns reddish. The brightness of the pale red is higher than that of red, but the brightness is reduced due to the reduction of the amount of red in the pale red, which means that the purity of the pale red is weakened compared to the red.

Purity reflects the introverted quality of color and is the spirit of color.

Purity is added to the gray stroke.

Brightness is the addition of black and white.

Difference Between Brightness and Purity:

1: Brightness is not the same as the definition of purity:

"Brightness" refers to how bright a color is. The intensity of light and darkness of a color due to the amount of light reflected by the color.

Purity refers to the degree of purity of a color, which indicates the proportion of color components contained in a color.

2: The conditions under which lightness and purity are expressed are different:

"Brightness" must be expressed by the light source, the color appears bright under strong light, and the color appears gray and blurry under low light.

The larger the proportion of color components, the higher the purity of the color, and the smaller the proportion of the color components, the lower the purity of the color.

3: The range of variation in the practical application of lightness and purity is different:

The range of "brightness" under the light source is "light" and "dark". The criterion for judging the brightness of a color.

"Purity" is the criterion for judging the brightness of the color in the range of "dark" and "light" changes in the color ratio.

The difference lies in the fact that "the purity contrast is the addition of gray and color, and the "brightness contrast" is the addition of black and white. The pure DAO degree is proportionally saturated.

Edition or freshness refers to the degree of brightness and color content of the color, and brightness refers to the brightness of the color.

Purity contrast] Purity contrast refers to the fact that the vividness of a color depends on the singularity of the light emitted by that hue. Different colors are put together, and their contrast is not the same. Colors that can be distinguished by the human eye with monochromatic light characteristics have a certain degree of vividness.

Different hues not only differ in brightness, but also in purity. It is with the change in purity that there is such a rich color in the world. Even a slight change in the purity of the same hue can bring about a change in the color character.

Brightness contrast] Brightness contrast is the contrast of the brightness and darkness of the color, also known as the contrast of black and white of the color. In psychology, brightness contrast is also known as chiaroscuro and brightness contrast. The brightness of the surface of an object is affected by the brightness of its different backgrounds, which makes individuals have different subjective lightness feelings.

For example, if two small squares are cut out of the same gray paper and placed on a white and black background paper, the individual will feel that the brightness of the small squares placed on the white background paper is darkened, and the brightness of the small squares placed on the black background paper is brightened, and the contrast of brightness is particularly obvious near the boundary between the small squares and the background.

Do you mean gouache before the exam? If this is the case, the purity contrast is simply that the more colors used in painting and toning, the lower the purity, and the fewer colors used, the higher the purity; The contrast of brightness is almost the black, white and gray mentioned in the sketch, and the color is heavy gray and bright.
