Colorless What is the color, and what colors are the achromatic system

Colorless means colorless, that is, so transparent that you can see the primary color on any color. Simply put, it is transparent white, and the transparent color of other colors is not colorless.

Achromatic refers to colors other than color, and the common ones are black, white, and gray. The luminosity varies from 0 to 100, while the chroma is very small and close to 0.

No color try to gradually add pure black to white, so that it is from black, dark gray, medium gray, light gray to pure white, divided into 11 steps, called brightness gradient, made into a brightness color scale, where the brightness in 0 ° 3 ° color is called low-key color, 4 ° 6 ° color is called medium color, 7 ° 10 ° color is called high color.

The size of the brightness difference between colors determines the strength of the brightness contrast, and the contrast within 3° is called the weak contrast of brightness, also known as short contrast. The contrast of 3° and 5° is called the middle contrast, and the hail is also called the middle contrast. Generally speaking, it is high-key and bright, low-key and simple, with a strong sense of time and a high degree of clarity of image; The contrast of brightness is weak, the sense of time is weak, and the source is unclear and ambiguous.

When the contrast of brightness is too strong, such as the longest tone, there are feelings of stiffness, hollowness, dazzling, simplification, etc., and there is a sense of horror.

The role of no color:

From a physical point of view, black, white and gray are not included in the visible spectrum, so they cannot be called colors. It should be pointed out that in psychology they have a complete color nature, and they also play an important role in the color system, and they also have their important tasks in pigments.

When a pigment is mixed with white, it will appear brighter; On the contrary, when mixed with black, it appears darker; When a mix of black and white is added, the chroma of the original color is promoted. Therefore, black, white, and gray can be called colors not only psychologically, but also physiologically and chemically.

Achromatic refers to white, black, and a variety of shades of gray formed by the combination of white and black.

Color refers to colors such as red, orange, yellow, green, cyan, blue, and purple. Achromatic refers to white, black, and a variety of shades of gray formed by the combination of white and black. According to a certain law of change, it can be arranged into a series of potato albums, from white gradient to light gray, medium gray, dark gray to black, colorimetric called this black and white series.

Green + blue is colorless. The three basic colors that can no longer be decomposed in the color, we usually say the three primary colors, that is, magenta, yellow, and cyan (cyan is not blue, and blue is the color of magenta and cyan mixed color). The three primary colors can be mixed to create all the colors, and at the same time they are added to black, and black, white, and gray belong to the colorless system.

Green represents the meaning of freshness, hope, safety, calm, comfort, life, peace, tranquility, nature, environmental protection, growth, vitality, youth, and relaxation. Green also has the meaning of pollution-free and healthy, such as green vegetables, etc., which is a common environmentally friendly color.

Conceptual analysis. People experience feelings of calm in environments with high-frequency colors such as green, blue, and purple, and are more likely to be excited and agitated in environments with low-to-medium frequency colors such as red, orange, and yellow. This phenomenon may have occurred in the course of human evolution.

Because for primitive humans, a green environment meant an abundance of food and water, and a positive feeling of green was integrated into the brain during evolution.

Green is the color of plants, and it also has the meaning of life in Chinese culture, which can represent nature, ecology, environmental protection, etc., such as green food. Green is associated with spring, so it symbolizes youth, but also symbolizes prosperity (taken from the leafy branches). The color green represents peace, friendliness, good listeners, and a character that does not want conflict.

Green plus yellow should equal five colors. When we were doing experiments in chemistry class, we did experiments like this, and I was very impressed.

What does colorlessness mean, is it transparent? Then I think the answer should be no. If colorless means white, then in terms of pigments, there is no feeling.

"Colorless" means "colorless".

"Color" means red, orange, yellow, green, cyan, blue, violet, or any of these seven colors. Regardless of the degree of inclusion of these seven color tendencies, they are all colored.

"Colorless" refers to 100% black, 100% white, and from 100% black to 100% white, the gray of each stage (gradient) formed in the process is "colorless". That is, colorless.

A solid color refers to a color or hue that is not mixed with other hues. The light beam or spectrum is a solid color, but it is not taken as one pigment or pigment does not contain certain components of the other color that is in this phase. In painting, a solid color can also mean a color that is extruded directly from a tin tube and is not mixed with other colors.

It is necessary to brighten up the colors with only white and darken them with more of the same color, and not use other colors. Purity color has a different meaning, and refers to the clarity of color according to the type of color. For example, alizarin has a pure and clear base, while India has a more cloudy base.

Purity of pigment means the absence of impurities.

Colorless, on the other hand, is a series of shades of gray obtained by mixing black and white in different proportions.
