What does color purity mean, lightness, purity, hue is what is the color?

Color purity is used to express the vividness and depth 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, it changes to a dull, hueless color.

When purity is minimized, it loses its hue and becomes colorless.

Color purity is calculated as a percentage and is expressed as an auxiliary to describe the color in terms of the dominant wavelength.

Brightness, purity, and hue are the three elements of color. Brightness is the brightness of a color, also known as dark and light colors, through which 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 to determine which color family it belongs to: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.

The purity of color refers to the brightness of the color, and the colors that we can recognize with a sense of hue have a certain degree of vividness.

All colors are composed of three primary colors, which are magenta, yellow, and blue (cyan). Primary colors have the highest purity, and the so-called color purity should refer to the percentage of primary colors in the color.

The degree of fresh gray of the color is the purity.

In color painting, try to use as few high-purity colors as possible, otherwise the picture will look "fire". Colors should be properly harmonized. For example:

When drawing a red apple, you should not paint it directly with red, but consider the color of the light source, the color of the interlining, the color of the surrounding objects, and the color change of the dark area.

Purity, one of the three elements of color, purity refers to the vividness of a single color! Primary colors are the most pure, and the more colors you add, the lower the purity!

It's like a glass of water, you add color to it, and the more you add it, the more turbid it becomes! The same thing!

Color purity: The percentage of primary colors in a color.

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.

Chinese name color purity shows the brightness and depth of color, the highest primary color, the lowest color, no color, simply called satura.

2 Composition. Colors of the same hue, not mixed with white or black, are called solid colors. Adding different brightness to the solid color without color will result in different purities. In the case of blue, if you add a little white to the pure blue, the purity decreases and the brightness increases, turning into a light blue.

Continue to add the amount of white, the color will become lighter and lighter, the purity will decrease, and the lightness will continue to rise. Conversely, if black or gray is added, the corresponding purity and brightness will be reduced at the same time.

All colors are made up of three primary colors, so the purity of the primary colors is the highest.

Color purity refers to the percentage of primary colors in a color.

Purity is used to express the vividness and depth 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 becomes dark and light.

The purity of a color refers to the degree of saturation of a color contained in a color. It indicates the proportion of color components contained in the color, the larger the proportion, the more color components are contained, and the higher the purity; The less color it contains, the lower the purity. If you want to unify the picture through purity, you can increase or decrease the purity of different colors at the same time to achieve a unified harmony of the color of the picture.

The contrast of colors

1. Color contrast.

Contrasts due to differences in hue. When the main hue is determined, it is necessary to consider what is the relationship between other colors and the main hue, what content and effect to be expressed, etc., so as to enhance its expressiveness.

2. Brightness comparison.

The contrast between the differences in brightness. Lemon yellow has high brightness, blue-violet lightness is low, and red and green belong to medium brightness.

3. Purity comparison.

When one color is less vivid than another, more vivid color, but when compared to a less vivid color, it appears vivid, and this color contrast is called purity contrast.

Purity usually refers to the vividness of a color. From a scientific point of view, the vividness of a color depends on the singularity of the light emitted by that hue. 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. In addition, chemical reagents are also divided into purity.

National standard reagents: This kind of reagents are stipulated in China's national standards and are suitable for inspection, identification and testing.

Reference reagent (PT, green label): used as a reference material to calibrate the standard solution.

Superior Grade Pure (GR, Guaranteed Reagent Green Label) (Grade 1): The main component content is very high, the purity is very high, suitable for accurate analysis and research work, and some can be used as reference substances.

The purity of color, also called saturation and saturation, is the standard used to express the vividness and depth of color. The higher the purity of a pure chongqing color, the more vivid the color, and if the purity gradually decreases, it will become darker and darker. The purest color is the primary color, while the lowest color becomes colorless.

In terms of visual efficacy, colors with high purity are easy to cause visual excitement because they are bright and gorgeous; The color tone of medium purity is relatively plump and soft, which can maintain people's vision for a long time; The color tone of low purity is more monotonous and durable, which is easier to make people relate.
