Color and color

[Convert] color scheme and color scheme

During the process of creating a webpage, I never knew how to set the color.

I mean, I don't know which colors should be put together. So yesterday, I found some information on the Internet and hoped to provide theoretical guidance.

The results were disappointing. Color theory studies the essence of color. As for color matching, it depends on personal feelings. After all, Choosing colors is art, not science. However, I 'd like to record some of the interesting items.

========================

1. Color Wheel

The so-called Color Wheel is to present a series of colors in order in the form of a disc.

It is generated by listing the primary colors (primary colors): red, yellow, and blue.

Then, the second and second COLORS are mixed to generate secondary colors (secondary colors): Green, orange, and purple.

Next, we continued to mix the second and second COLORS and produced six third-level COLORS (tertiary colors): yellow orange, red orange, red purple, blue purple, yellow green, and blue purple.

By constantly mixing adjacent colors, a new Color is generated to form a global Color Wheel.

2. Similar colors and complementary colors

Any three adjacent colors on the 12-Color Wheel are called analogous colors ). They are usually considered to be harmonious.

The two colors on the diagonal lines of Color Wheel are called complementary colors (complementary colors ). They are generally considered to be compared if they are put together.

In addition, if you want to find three balanced colors, you can select a 12-Color ).

If you want to find three colors, two of which are similar to each other, and the other is compared with them, you can select adjacent colors on both sides of the complementary colors. (Split-complementary colors)

3. Color Model

There are three common color models: RGB, CMYK, and HSV.

4. RGB model

RGB is short for Red, Green, and Blue. Any color can be mixed by different proportions of Red, Green, and Blue. This model is mainly used for color display on the electronic display screen.

The RGB model usually uses three hexadecimal numbers to represent the color. FFFFFF represents the red color of 100%, the green color of 100%, and the blue color of 100%; 000000 represents the red of 0%, the green of 0%, and the blue of 0%, resulting in black.

5. HSV Model

H refers to Hue, a synonym for "color.

S refers to Saturation (Saturation), which refers to the color purity, that is, the color contains the degree of gray. The higher the saturation, the more pure the color; the lower the saturation, the greater the gray component in the color. When the saturation value of any color changes to the minimum value, it turns gray.

V indicates the Value, that is, the white component in the color. The larger the value, the brighter the color. The smaller the value, the darker the color. At the maximum value, all colors are white, and at the minimum value, all colors are black.

The HSV model identifies the color by adjusting these three values. It is usually in the form of color wheel. The color of all edges is the color with the highest saturation, and the smaller the saturation to the center of the circle. Hue selects the angle Value and a brightness axis to select the Value.

6. CMYK Model

This model is mainly used in the printing industry to produce other colors by mixing the four pigments cyan, magenta, yellow, and black.

The pattern on the print is actually made up of small dots, and each small dot is made up of four colors. After overlapping, various colors are produced.
