Does red refer to the hue, brightness, or purity of the color?

Hue. Hue, that is, the physiognomy of various colors, such as red, blue, lemon yellow, etc. Hue is the primary characteristic of color and is the most accurate criterion for distinguishing different colors.

In fact, any color other than black, white, and gray has the property of hue, and hue is composed of primary, interchromatic, and compound colors.

Brightness refers to the brightness of the color, different colors have different brightness, for example, yellow is higher than blue, how to arrange different brightness of color blocks in a picture can also help express the feelings of the painting, if the sky is lower than the ground brightness, it will produce a feeling of oppression. There are light and dark variations in any color. Among them, yellow has the highest brightness, purple has the lowest, and green, red, blue, and orange have similar brightness, which is the middle lightness.

In addition, there are variations in the lightness of the same hue. For example, there are changes in brightness such as pink green, light green, and emerald green from light to dark in green.

Purity is the name that describes the color quality, also known as saturation or saturation, freshness. The purity of a color refers to the degree to which the hue feels clear or vague, vivid or cloudy. The addition of white or black to high-purity hues can increase or decrease their brightness, but both will reduce their purity.

If you add neutral gray, it will also reduce the purity of the hue. In painting, it is mostly a compound color with two or more pigments of different hues. According to the color arrangement of the color wheel, the adjacent hues are mixed, and the purity is basically unchanged (such as the orange obtained by mixing the red and yellow phases).

Mixing contrasting hues is the most likely to reduce purity to the point that it becomes a gray color. The change of color purity can produce rich hues of different strengths and weaknesses, and make the color produce charm and beauty.

There's ambiguity"Red"Refers to hue,"Great"It also indicates its purity.

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.

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. Add black or gray and the corresponding purity and brightness are reduced at the same time.

All colors are composed of three primary colors, namely red (rose red), 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.

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.

Purity refers to the dark and light colors of the color range.

Color purity refers to the percentage of primary colors in a color. Purity is used to express the brightness and depth of color, the purest color is the primary color, with the reduction of purity, the color will become dark and light. 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 color, the more vivid the color will be, 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 effect, 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.

The contrast of colors

Color contrast. The contrast between the differences between the color deficits. 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.

Brightness contrast. 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.

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.

Warm and cold contrast. The color contrast formed due to the difference between warm and cold colors is called warm and cold contrast. Red, orange and yellow make people feel warm; Blue, blue-green, blue-purple make people feel cold; In addition, the contrast between cold and warm colors is also affected by brightness and purity, white light has a high reflection and feels cold, and black has a high absorption rate and feels warm and warm.

Complementary color contrast. The juxtaposition of colors with complementary color relationships, such as red and green, yellow and purple, and blue and orange, makes the color feel more vivid and the purity increases, which is called complementary color contrast.

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

The purity of the color of the oak reed, is relative.

It refers to a mixture of two colors, and the purity of a single color is 100%, that is, the purity is the highest, such as the red beam, the blue, and the yellow (here specifically refers to the pigment, that is, the common pigments and dyes.)

Class I) Pink has low purity relative to red, orange has low purity relative to positive yellow, and the brightness of the color.

It refers to the brightness and darkness of the color, that is, the mixing degree of ordinary colors when mixed with black, and the more black is added, the lower the brightness.

The hue of a color refers to the feeling of warmth and coldness of a color, such as warm red and cold blue, but these are also relative.

When you say satura, in terms of professional terms, there is no such statement, you should mean brightness!
