Color basics

To understand and use colors, you must master the principles and methods for color generalization. Among them, the most important thing is to grasp the color attributes.
Color, which can be divided into two categories: no color and no color. The former is black or white. Gray, the latter such as red, yellow, blue and other colorful.
Color indicates the color of certain or certain colors in the spectrum. In contrast, there is no color tone without color.
The color is white, black, and also called the color. The color representation is very complex, but it can be determined by using three special micro values. The first is the color tone, that is, the color phase; the second is the light and shade, that is, the brightness; the third is the color intensity, that is, the purity and color. Brightness and color level determine the color status. It is called the three attributes of color. Brightness and color are merged into the color State of the second line, called the color. Some people regard brightness as a tone, which is not comprehensive.

Brightness
When talking about brightness, we recommend that you have no color staff, because no color is only one-dimensional, and there are many arguments. (Figure) the brightest is the white, the lowest is the black, and the gray of different degrees between the black and white, all have the intensity of light and shade. If it is divided by a certain interval, it constitutes a light and shade scale. Color refers to the brightness value of the user, and addition and subtraction of gray and white adjust to adjust the brightness and shade.
Japanese color Research color system (P. C. S.) uses nine levels, and Menser uses eleven levels to express brightness. Both use a series of numbers to express the rapid increase of brightness. The brightness of an object, which is related to its surface reflectivity. If there are many reflections, less absorption will be bright; on the contrary, it will be dark. Only of the reflected light is the ideal white light. Of the reflected light is the ideal black light. There is no such ideal phenomenon around us, so people often regard the recently ideal white Magnesium sulfide crystalline surface as the white standard. In the P. C. S. System, the black value is '1, and the gray tuning times are 2.4.3.5, 4.5. 5.5, 6.5, 7.5, and 8.5. The White value is 9.5. The more you turn to white, the higher the brightness, the more you turn to black, the lower the brightness. The general classification includes the highest, high, slightly higher, medium, slightly lower, low, and lowest seven levels. In the middle of Level 9, if their division is added, that is, 2, 3, 4, 5, 6, 9, then 17 brightness levels are required.
Color Brightness indicates the brightness of the color, and the brightness of the purity indicates the brightness of the color. The brightness is generally marked by vertical and vertical. The top is the white, the bottom is the black, and then according to the feeling of sending the adjustment level, discharged into the gray tune. 'This indicates the vertical axis of light and shade, which is called the non-color axis. It is the central axis of the color.

Color

Color is the color that contains the red, yellow, blue and other color families, these are called the color.
The basic colors are red, orange, yellow, green, blue, and purple. Add one or two middle colors in the middle of each color. The first and end colors are in the spectral order: red, orange, yellow, green, green, blue, purple, red. Red and Purple plus a middle color, can produce 12 basic colors.
The color adjustment of these twelve colors is even in the spectral color sense. If we further find out the color between them, we can get twenty-four colors. If the red, orange, green, blue, and purple bands of the spectrum are circled, half of the red and purple bands are inserted to form a ring-shaped relationship, which is called the color scheme. The basic colors take the middle colors, that is, twelve colors. The next step is the twenty-four colors. In the circle of the colors, the colors are arranged in different angles, and the distance between each color of the twelve colors is 30 degrees. The spacing of each color of the twenty-four colors is 15 degrees.
The P. C. C. s system makes a unified name and symbol for the color. Among them, red, orange, yellow, green, blue, and purple refer to their "positive" colors (of course, the so-called positive colors are not the same as those in different regions ). The normal color is represented by a single uppercase letter, and the same amount of mixed colors are represented by two parallel uppercase letters. The unequal amount of mixed colors are mainly uppercase letters, and the color is lowercase letters. The only exception is that blue-violet uses V instead of BP. V is the first letter of violet. It is a color-coded letter, which is easy to use and easy for beginners to remember.
In this way, the Japanese people divide and set their color names. Obviously, they are in combination with the ten-color and twenty-color of Mensel. The Mensel system uses red, yellow, green, blue, and purple colors as the basic colors and calls it yellow red. Therefore, the twenty-four colors of P, C, C, and S are also classified into ten categories,

Color

A color-and-phase tone can also be divided into strengths and weaknesses. Take Zheng Hong for example, there are bright pure red without impurities, there is a dry and residual "withered rose", there is also a weak pink. They have the same color, but different strengths and weaknesses. They are generally referred to as (Sa + ura + lOn) or colors. The higher the color, the more pure the color. The lower the color, the more sexy the color. Solid color is the highest level of color.
Color level. Generally, horizontal axis is used. take the non-color vertical axis as the point, stretch in the direction of a certain color phase in the color, according to the color level from low to high for several levels, P, C, C, S system will be divided into nine levels, the unit is S. The minimum IS.
The maximum value is g S. The closer it is to the colorless vertical axis, the lower the color. There is no color tone on the non-color axis. The color is o s. Far from the colorless axis, the color is high, and the endpoint is the solid color, that is, the color of the spectrum.
The color level is classified as follows: find the gray adjustment corresponding to the brightness of the purity, and add them to the solid color one by one based on the feeling, at the same time, one copy of the appointment color is deducted one by one. Then we get eight consecutive colors of solid colors. 5 S is to buckle to 4/9 solid color to add 4/9 ash; ISG is to buckle to 8/9 purity, added 8/9 solid color, added 8/9 ash.
The general classification method corresponds to the level 9 color. It is marked with five levels: high, slightly higher, medium, slightly lower, and low.
Stereo Color mark
We organize the brightness, hue, and color obtained from the preceding mixing under the white light, and choose from the bottom to the top. The color labels on each cross section are the same, the color of the upper cross section is higher than that of the lower cross section. Then, the black, white, and Gray are used as the central axis, and the center is out. The purity of the color mark is the same on the same cylinder, and the purity of the cylindrical column is higher than that on the internal cylinder. The central axis of the team goes outward, and the colors of each profile are the same, make the colors of different profile different red, orange, yellow, green, green, blue, purple and other colors from the central axis of the cycle column according to the time needle sequence, in this way, thousands of color labels are strictly organized to become three-dimensional color labels. Currently, the three-dimensional color labels that have a major impact are the OSS Thua and Musel colors.
