How colors are formed How colors are made

Light is formed by the spectrum of light spectrum, and the rainbow is a good proof of this. By refracting sunlight with a prism, you can see colorful colors. Various objects absorb different wavelengths of light, and those that absorb more can show color, and those that cannot absorb can not be revealed.

Color is a subjective sensation produced by our human eyes when they receive light at different frequencies. Color is the light emitted, reflected, or transmitted by objects of different frequencies into our eyes, and our eyes have different color perceptions of different frequencies of light.

Reflection of light! There are various color elements in various colors, and many colors can appear due to the reflection of light! There are two kinds of complementary colors, you can learn artistic colors!

Color is formed due to the refraction of light inside the eye, and what color is formed is related to the structure of the eye, and the color seen by humans and animals is different.

Formed by the reflection and transmission of light.

Formed by reflecting sunlight.

Visual fibers capture the results of different wavelengths of light.

Hello, color is produced by the light reflected or absorbed by an object. When light hits the surface of an object, the object absorbs some of the light and reflects the other. The colors we see are the light that is reflected back.

For example, a white object reflects all the light, so it appears white; Black objects absorb all light so that they cannot be reflected back. Other colors are formed by absorbing and reflecting light of different wavelengths. For example, a green object absorbs the red and blue rays of all the light and reflects back the green rays, giving it a green appearance.

Extended Supplement: Color is very important in our lives. In art and design, color can be used to express emotions and moods, creating visuals and aesthetics.

In science and engineering, color is also very important, it can be used to identify the properties and properties of a substance, such as the color of a chemical reagent to determine whether a substance is present. In addition, the color can be used for positioning and marking, e.g. the color code can be used to identify the function and position of the wire. Therefore, as a part of visual expression, color has a wide range of applications and profound meaning for our lives.

1. The production of color is caused by the different wavelengths in the eyes, and the color of the object is determined by the frequency of the light waves that enter the human eye.

2. The colors include the color of the luminous body and the color of the non-luminous body.

3. The object that can emit light by itself is called the light source, and the light source can be divided into two categories, one is the thermal radiation light source, and the other is the non-thermal radiation light source.

The production of color: the three primary colors of light, redGreen, blue

The three colors of light are mixed according to different brightness, and a few slips can produce any color, and the overlapping of the three colors will become white.

The relationship between light and color

When we look at a red apple, we see that the color is red because the apple only reflects the red red, and the apple absorbs other light. When we use red light to shine on a green object, because the green object only reflects green light, and if we use red light, there is no green light reflection, so it is already black!

To put it simply, an object does not absorb any color, and we see it with the naked eye. Any substance has its own pigments, these pigments will not react under the condition of no light, once irradiated by light, some pigments will undergo that change, the light that irradiates itself will be absorbed, and those pigments that have not changed will reflect the light.

Expand your knowledge:

What the human eye sees is actually reflected by pigments in objects that cannot absorb light. All around us, all kinds of substances have a certain color, yellow soil, green woods, red blood, blue ocean, various substances of different colors, make up this colorful world. It's not hard to imagine how dull and rigid our world would be without color.

Without color, our lives would be so boring! Colors not only decorate the earth and the universe; Color, but also give us infinite vitality and infinite happiness for human beings! Colors not only adorn the whole world, but are becoming more and more versatile.

Humans have been paying attention to the use of color from the very beginning.

For example, lacquer paintings and porcelain in ancient China are good examples of our ancestors' skillful use of color. In our daily lives, we often use colors to distinguish various objects. With the improvement of people's living standards, the clothes they wear every day should not only be warm, but also beautiful.

People's diet is no longer limited to food and clothing, but requires color, aroma, and taste, that is, not only to be delicious, but also to look good, and so on, color plays a very important role. In analytical chemistry, the amount of substance content is often determined according to the color of the substance; Biochemists often use color for tissue studies.
