There are many colors in nature, such as bananas are yellow, the sky is blue, and oranges are orangeColorful and ever-changing.The light we see everyday is actually composed of three wavelengths of light: red, green and blue. The object is irradiated by the light source, absorbs and reflects red, green and blue light of different wavelengths, and transmits it to the brain through the human eyes to form various colors we see.In other words, the color of objects is the color of the light they reflect.Red, green and blue wavelengths of light are the basis of all colors in nature, and all colors in the spectrum are composed of different intensities of these three lights.
We live in a colorful world. The sky, grass and sea have their own colors.You, I and he also have their own colors. The colors of clothing, home decoration and decorations representing their own characteristics can fully reflect people's personality, hobbies and taste.Color is generally divided into two categories: colored and achromatic. 1、 Colored
The color with a certain standard color tendency (that is, the color with a cold and warm tendency) is called with color.All colors in the spectrum are colored.There are countless colors. It takes red, orange, yellow, green, blue and purple as its basic colors.Website designThe mixing of different amounts of basic colors, as well as the mixing of basic colors with black, white and gray (no color), will produce thousands of colors.
What we see is that there are color series, and these colors often give people a relative, changeable and abstract psychological feeling.Color is determined by the wavelength and amplitude of light. The wavelength determines the hue, and the amplitude determines the hue, as shown in the following figure.
There are six standard colors: red, orange, yellow, green, blue and purple.The six colors are subdivided into three primary colors and secondary colors.
The three primary colors are red, yellow and blue, as shown in the figure below. The secondary colors are orange, purple and green, which lie between the three primary colors and form another equilateral triangle, as shown in the right figure below. Through comparison, it can be found that in the above six color arrangement, the primary color is always separated by a secondary color, so just remember the standard color to distinguish the primary color and secondary color.
Color rings are formed by arranging the color system into a circle in order.Color rings play a very important role in understanding the relationship between colors.The non color system and the color system form a unified color whole that is different from each other and share weal and woe.As shown in the figure below, there are colorful pages, red color combination, open and easy-going.It also has all the elements of energy and power, which can create a festive and festive atmosphere.
2、 Achromatic
Achromatic is a series of grey with different shades obtained by mixing black, white and the two in different proportions.The three colors cannot be seen on the light chromatography, and they are not included in the visible spectrum, so they are called achromatic, as shown in the following figure.
