Color code table. Color in styles can be set in different ways: by hexadecimal value, by name, in RGB, RGBA, HSL, HSLA format

The CSS color module details the values ​​that allow authors to define the colors and opacity of html elements, as well as the values ​​of the color property.

Color property

1. Priority colors: the color property

The property sets the color of the font using various color rendering systems. The property describes the color of the text content of the element. It is also used to provide a potential indirect value (currentColor) for any other properties that accept color values.

The property is inherited.

2.2. Numerical color values

2.2.1. RGB colors

The RGB hexadecimal value format is a # sign immediately followed by three or six hexadecimal characters. Three-digit RGB #rgb is converted to six-digit #rrggbb by copying digits rather than adding zeros. For example, # fb0 expands to # ffbb00. This ensures that white #ffffff can be specified in the short #fff, and removes any color depth dependencies from the display.

The RGB value format in functional notation is rgb (followed by a comma-separated list of three numeric values ​​(either three integer values ​​or three percent values) followed by a character). The integer value 255 corresponds to 100% and F or FF in hexadecimal notation:

Rgb (255,255,255) = rgb (100%, 100%, 100%) = #FFF

Space characters are allowed around numeric values.

In HTML, a color is specified in one of two ways: using a hexadecimal code and by the name of some colors. The method based on the hexadecimal number system is mainly used, as the most universal one.

Hexadecimal colors

Hexadecimal numbers are used to specify colors in HTML. The hexadecimal system, in contrast to the decimal system, is based, as its name suggests, on the number 16. The numbers will be as follows: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C , D, E, F. Numbers from 10 to 15 are replaced by Latin letters. Table 6.1 shows the correspondence between decimal and hexadecimal numbers.

Numbers greater than 15 in the hexadecimal system are formed by combining two numbers into one (Table 6.2). For example, 255 decimal is FF hexadecimal.

To avoid confusion in the definition of the number system, the hash character # is placed in front of the hexadecimal number, for example # aa69cc. In this case, the register does not matter, so it is permissible to write # F0F0F0 or # f0f0f0.

A typical color used in HTML looks like this.

Here, the background color of the web page is set to # FA8E47. The hash symbol # in front of a number means it is hexadecimal. The first two digits (FA) define the red component of the color, the third through fourth digits (8E) are green, and the last two digits (47) are blue. As a result, you get this color.

Each of the three colors - red, green, and blue - can take on values ​​from 00 to FF, resulting in 256 shades. Thus, the total number of colors can be 256x256x256 = 16.777.216 combinations. The color model based on red, green and blue components is called RGB (red, green, blue; red, green, blue). This model is additive (from add - to add), in which the addition of all three components forms a white color.

To make it easier to navigate in hexadecimal colors, take some rules into account.

• If the values ​​of the color components are the same (for example: # D6D6D6), then you get a gray tint. The higher the number, the lighter the color, the values ​​vary from # 000000 (black) to #FFFFFF (white).
• A bright red color is formed if the red component is set to maximum (FF), and the rest of the components are set to zero. The color # FF0000 is the reddest possible red tint. The same is the case with green (# 00FF00) and blue (# 0000FF).
• Yellow (#FFFF00) is obtained by mixing red with green. This is clearly visible on the color wheel (Fig. 6.1), where the primary colors (red, green, blue) and complementary or complementary colors are presented. These include yellow, cyan, and purple (also called magenta). In general, any color can be obtained by mixing nearby colors. So, cyan (# 00FFFF) is obtained by combining blue and green.

Hexadecimal colors do not need to be chosen empirically. For this purpose, a graphic editor that can work with different color models is suitable, for example, Adobe Photoshop. In fig. 6.2 shows a window for choosing a color in this program, the resulting hexadecimal value of the current color is outlined with a line. You can copy and paste it into your code.

Web colors

If you set the color quality of the monitor to 8 bit (256 colors), then the same color can be displayed differently in different browsers. This is due to the way graphics are displayed, where the browser is working with its own palette and cannot show a color that it does not have in the palette. In this case, the color is replaced by a combination of pixels of other, close to it, colors that imitate the specified one. To keep the color unchanged in different browsers, we introduced a palette of so-called web colors. Web colors are those colors, for each component of which - red, green and blue - one of six values ​​is set - 0 (00), 51 (33), 102 (66), 153 (99), 204 (CC), 255 (FF). The parentheses indicate the hexadecimal value of this component. The total number of colors from all possible combinations gives 6x6x6 - 216 colors. An example of a web color is # 33FF66.

The main feature of web color is that it appears the same across all browsers. At the moment, the relevance of web colors is very small due to the increase in the quality of monitors and the expansion of their capabilities.

Colors by name

In order not to memorize a set of numbers, you can use the names of commonly used colors instead. Table 6.3 lists the names of popular color names.

It doesn't matter in which way you specify the color - by its name or using hexadecimal numbers. These methods are equal in their action. Example 6.1 shows how to set the background and text color of a web page.

Example 6.1. Background and text color

Sample text

In this example, the background color is set using the bgcolor attribute of the tag , and the text color through the text attribute. For a change, the text attribute is set to a hexadecimal number, and bgcolor is set to the teal reserved keyword.

Minecraft cheats colors, or Minecraft codes formatting, allow any player to add flowers and format text in every way right in Minecraft. Color codes& 0-9 - to & a-f. Add them in front of your text. Player messages may contain color codes that allow you to add paint to your suggestions.

The ampersand (&) followed by a hexadecimal number in messages signals the client to switch colors when displaying text. Alternatively, text can be formatted with the character & followed by a letter. You can add different colors to books, command blocks, server name, server description ( motd), in the names of worlds, in tablets and even in names players.

It is very easy to format your text in configs or in the game using the color table below. & r is used to clear all codes, i.e. & mAAA & rBBB will be displayed as AAA BBB.

Sometimes you need underline, cross out, highlight any text... For this, text formatting is used. It is used in the same way as colors (in front of the text we put the code e.g. & lMinecraft = Minecraft.

There are several ways to represent color in web design.

HEX is a base 16 hexadecimal color representation system. For this system, Arabic decimal digits from 0 to 9 and Latin letters from A to F are used to complement the digital number to 16. For web design, 16 basic (key) colors are taken, the so-called hexadecimal color code #RRGGBB, where each pair is responsible for its share of the color: RR - red, GG - green and BB - blue. Each color fraction ranges from 00 to FF.

Two other representations of color in web design are: in the form of RGB (*, *, *), where each "*" color fraction is represented by decimal digits from 0 to 255 and by color names in English.

When creating a color image, the main problem is the correct rendering of colors on different types of computers, monitors and browsers. If the browser cannot display a color correctly, then it picks up a similar one or mixes several colors. And sometimes it can be replaced with some completely different color.

Hexadecimal numbers are used to set colors. The hexadecimal system, in contrast to the decimal system, is based, as its name suggests, on the number 16. The numbers will be as follows: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C , D, E, F. Numbers from 10 to 15 are replaced by Latin letters. Numbers greater than 15 in hexadecimal are formed by combining two numbers into one. For example, 255 decimal equals FF hexadecimal. To avoid confusion in the definition of the number system, the hash symbol # is placed in front of the hexadecimal number, for example # 666999. Each of the three colors — red, green, and blue — can range from 00 to FF. Thus, the color designation is divided into three components #rrggbb, where the first two characters mark the red component of the color, the two middle ones - green, and the last two - blue. It is allowed to use an abbreviated form like #rgb, where each character should be doubled. So, the # fe0 entry should be treated as # ffee00.

By name

Browsers support some colors by name. Table 1 shows the names, hexadecimal code, RGB, HSL values ​​and description.

With RGB

You can determine the color using the decimal values ​​of the red, green, and blue components. Each of the three color components takes a value from 0 to 255. It is also permissible to set the color as a percentage, while 100% will correspond to the number 255. First, the rgb keyword is specified, and then in parentheses, the color components are indicated, separated by commas, for example rgb (255 , 128, 128) or rgb (100%, 50%, 50%).

RGBA

The RGBA format is similar in syntax to RGB, but includes an alpha channel that controls the transparency of the element. A value of 0 corresponds to full transparency, 1 to opacity, and an intermediate value like 0.5 to semi-transparency.

RGBA was added in CSS3, so CSS code validation should be done using this version. It should be noted that the CSS3 standard is still under development and some features may change. For example, an RGB color added to the background-color property is validated, but a color added to the background property no longer. At the same time, browsers quite correctly understand the color for both properties.

Hsl

The name of the HSL format is formed from a combination of the first letters Hue (hue), Saturate (saturation) and Lightness (lightness). Hue is the value of a color on the color wheel (Fig. 1) and is given in degrees. 0 ° is red, 120 ° is green, and 240 ° is blue. The hue value can range from 0 to 359.

Saturation is the intensity of a color, measured as a percentage from 0% to 100%. A value of 0% denotes no color and a shade of gray, 100% is the maximum saturation value.

Lightness sets how bright the color is and is indicated as a percentage from 0% to 100%. Low values ​​make the color darker, and high values ​​lighten, extreme values ​​of 0% and 100% correspond to black and white.

HSLA

The HSLA format is similar in syntax to HSL, but includes an alpha channel that sets the transparency of the element. A value of 0 corresponds to full transparency, 1 to opacity, and an intermediate value like 0.5 to semi-transparency.

Color values ​​in RGBA, HSL, and HSLA formats have been added in CSS3, so be sure to check for version validity when using these formats.
