Dark what color. Color in styles can be specified in different ways: by hexadecimal value, by name, in RGB, RGBA, HSL, HSLA format. Using RGB

The CSS color module details 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: color property

The property sets the font color using various systems color rendition. The property describes the color of the element's text content. Additionally, it is used to provide a potential indirect value (currentColor) for any other properties that accept color values.

The property is inherited.

2.2. Numeric color values

2.2.1. RGB model colors

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

The format of an RGB value in functional notation is rgb(followed by a comma-separated list of three numeric values ​​(either three integer values ​​or three percentage values) followed by a symbol). 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.

HTML colors are indicated by six characters after the slash character - for example, #000000. These six symbols represent the proportions of the different colors (Red, Green, Blue) in the final color. On your computer monitor, the image is formed from a huge number of dots called pixels. Each pixel is a small light source, let's call it a "flashlight", which in turn consists of three flashlights - red, green and blue. By decreasing or increasing the intensity of the glow of individual colored flashlights, we obtain the desired color.

HTML color codes

Colors in HTML are represented by a hexadecimal (HEX) notation of red, blue, and green (RGB).

The smallest color value is 0 (hexadecimal 00). The highest color value is 255 (hex FF).

The hexadecimal color value is three digits starting with the # sign.

16 million shades

Combining red, blue, and green with values ​​ranging from 0 to 255 for the percentage of each color results in a total of over 16 million shades (256 x 256 x 256).

Most modern monitors are capable of displaying at least 16,384 different shades (LCD monitors are generally capable of displaying 262 thousand 16 million (updated October 2013) colors, and CRT monitors can display a virtually unlimited number of colors).

The color table below shows the change in the proportion of red from 0 to 255 with zero values ​​for blue and green:

Cross-browser (all browsers) html color names

A collection of 150 color names in html, supported in all browsers.

Standardized color names

The W3C lists 16 valid color names for HTML and CSS: aqua, black, blue, fuchsia, gray, green, lime, maroon (chestnut), navy (ultramarine), olive (olive), purple (purple), red (red), silver (silver), teal (gray), white (white) and yellow (yellow).

When using colors not included in this list, it is more correct to use their hexadecimal (HEX) code or RGB code.

Safe colors

Several years ago, when computers could support a maximum of 256 different colors, a list of 216 "Web Safe Colors" was proposed, with 40 colors reserved for the system.

This 216-color palette was created to properly display colors in the 256-color palette mode.

Now this doesn't matter because most computers around the world support millions of shades of color. In any case, here is a list of these colors:

This page contains a table with keywords that can be used to denote colors in such Web developer languages ​​as: HTML, CSS, JavaScript, Flash, etc.

In the old specifications for the WC3 concern, only 16 keywords were specified, with the help of which colors were set in HTML and CSS. In further, more modern specifications, another 130 keywords were added to indicate color names. The following table contains the color names and the hex and RGB codes they correspond to.

In accordance with CSS rules color names are not case sensitive. The color entries IndianRed and indianred are equivalent.

It is also worth noting that of the 146 keywords in the table, there are actually fewer colors in it. This is because some keywords refer to the same color. Thus, the names Gray and Gray represent the 50% gray color code #808080, and the word Magenta is a synonym for the HTML color Fuchsia, corresponding to the hexadecimal code #FF00FF. Also synonymous are the words Aqua and Cyan, they correspond to the code #00FFFF.

Hexadecimal numbers are used to specify colors. The hexadecimal system, unlike 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 with Latin letters. Numbers greater than 15 in the hexadecimal system are formed by combining two numbers into one. For example, the number 255 in decimal system corresponds to the number FF in hexadecimal. To avoid confusion in determining the number system, before hexadecimal number put the hash symbol #, for example #666999. Each of the three colors - red, green and blue - can take values ​​from 00 to FF. Thus, the color symbol is divided into three components #rrggbb, where the first two symbols indicate the red component of the color, the middle two - green, and the last two - blue. It is allowed to use the abbreviated form #rgb, where each character should be doubled. Thus, the entry #fe0 should be regarded as #ffee00.

Using RGB

Internet Explorer Chrome Opera Safari Firefox Android iOS
5.0+ 1.0+ 3.5+ 1.3+ 1.0+ 1.0+ 1.0+

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

RGBA

Internet Explorer Chrome Opera Safari Firefox Android iOS
9.0+ 1.0+ 10.0+ 3.1+ 3.0+ 2.1+ 2.0+

The RGBA format is similar in syntax to RGB, but includes an alpha channel that specifies the transparency of the element. A value of 0 is fully transparent, 1 is opaque, and an intermediate value like 0.5 is semi-transparent.

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

HSL

Internet Explorer Chrome Opera Safari Firefox Android iOS
9.0+ 1.0+ 9.6+ 3.1+ 3.0+ 2.1+ 2.0+

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

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

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

HSLA

Internet Explorer Chrome Opera Safari Firefox Android iOS
9.0+ 1.0+ 10.0+ 3.1+ 3.0+ 2.1+ 2.0+

The HSLA format is similar in syntax to HSL, but includes an alpha channel to specify the element's transparency. A value of 0 is fully transparent, 1 is opaque, and an intermediate value like 0.5 is semi-transparent.

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

Color codes in CSS are used to specify colors. Typically, color codes or color values ​​are used to set the color for either the foreground color of an element (e.g. text color, link color) or the background color of an element (background color, block color). They can also be used to change the color of a button, border, marker, hover, and other decorative effects.

You can specify your color values ​​in various formats. The following table lists all possible formats:

The listed formats are described in more detail below.

CSS Colors - Hex Codes

Hexadecimal color code is a six-digit representation of color. The first two digits (RR) represent the red value, the next two represent the green value (GG), and the last two represent the blue value (BB).

CSS Colors - Short Hex Codes

Short hex color code is a shorter form of six-character notation. In this format, each digit is repeated to produce an equivalent six-digit color value. For example: #0F0 becomes #00FF00.

Hexadecimal value can be taken from any graphic software, such as Adobe Photoshop, Core Draw, etc.

Each hexadecimal color code in CSS will be preceded by a hash sign "#". Below are examples of using hexadecimal notations.

CSS Colors - RGB Values

RGB value is a color code that is set using the rgb() property. This property takes three values: one each for red, green, and blue. The value can be an integer, from 0 to 255, or a percentage.

Note: Not all browsers support the rgb() color property, so it is not recommended to use it.

Below is an example showing multiple colors using RGB values.
