The basic colors are 16 colors defined in the HTML 4.01 specification, ratified in 1999, as follows (names are defined in this context to be case-insensitive):ĬSS 1–2.0, HTML 3.2–4, and VGA color names

In HTML and XHTML, colors can be used for text, background color, frame borders, tables, and individual table cells. Recent W3C specifications of color names distinguishes between basic and extended colors. Web-based tools specifically for converting color values are also available.

This process is repeated for each of the three color values.Ĭonversion between number bases is a common feature of calculators, including both hand-held models and the software calculators bundled with most modern operating systems. A remainder of nine gives the hexadecimal number C9. For instance, the RGB value 201 divides into 12 groups of 16, thus the first digit is C. The remainder gives the second hexadecimal digit.

This number divided by sixteen (integer division ignoring any remainder) gives the first hexadecimal digit (between 0 and F, where the letters A to F represent the numbers 10 to 15. RGB values are usually given in the 0–255 range if they are in the 0–1 range, the values are multiplied by 255 before conversion. Expanding this form to the six-digit form is as simple as repeating each digit: 09C becomes 0099CC as presented on the following CSS example: The number of colors that can be represented by this system is 16 6 or 256 3 or 2 24 = 16,777,216.Īn abbreviated, three (hexadecimal)-digit or four-digit form can be used, but can cause errors if software or maintenance scripts are only expecting the long form. For example, the decimal triplet 4, 8, 16 would be represented by the hex digits 04, 08, 10, forming the hex triplet 040810.

If any one of the three color values is less than 10 hex (16 decimal), it must be represented with a leading zero so that the triplet always has exactly six digits. The hex triplet is obtained by concatenating the six hexadecimal digits together, 2468A0 in this example. The decimal numbers 36, 104, and 160 are equivalent to the hexadecimal numbers 24, 68, and A0 respectively. The hex triplet is formed by concatenating three bytes in hexadecimal notation, in the following order:įor example, consider the color where the red/green/blue values are decimal numbers: red=36, green=104, blue=160 (a grayish-blue color). Thus web colors specify colors in the 24-bit RGB color scheme. This represents the least (0) to the most (255) intensity of each of the color components. One byte represents a number in the range 00 to FF (in hexadecimal notation), or 0 to 255 in decimal notation. The optional fourth byte refers to alpha channel. The bytes represent the red, green, and blue components of the color. More advanced user agents use color management to provide better color fidelity this is particularly important for Web-to-print applications.Ī hex triplet is a six-digit (or eight-digit), three- byte (or four-byte) hexadecimal number used in HTML, CSS, SVG, and other computing applications to represent colors. User agents vary in the fidelity with which they represent the specified colors. These have been chosen to be similar to many real-world monitors and viewing conditions, to allow rendering to be fairly close to the specified values even without color management. Web colors have an unambiguous colorimetric definition, sRGB, which relates the chromaticities of a particular phosphor set, a given transfer curve, adaptive whitepoint, and viewing conditions. The first versions of Mosaic and Netscape Navigator used the X11 color names as the basis for their color lists, as both started as X Window System applications. It is impossible with the hexadecimal syntax (and thus impossible in legacy HTML documents that do not use CSS). Specifying a non-sRGB color this way requires the RGB() function call. Thus, there are 24 bits used to specify a web color within the sRGB gamut, and 16,777,216 colors that may be so specified.Ĭolors outside the sRGB gamut can be specified in Cascading Style Sheets by making one or more of the red, green and blue components negative or greater than 100%, so the color space is theoretically an unbounded extrapolation of sRGB similar to scRGB. A color is specified according to the intensity of its red, green and blue components, each represented by eight bits. In some uses, hexadecimal color codes are specified with notation using a leading number sign (#).

A color tool or other graphics software is often used to generate color values. Web colors are colors used in displaying web pages on the World Wide Web they can be described by way of three methods: a color may be specified as an RGB triplet, in hexadecimal format (a hex triplet) or according to its common English name in some cases.
