HTML web colors are colors used in displaying web pages, and the approach for characterizing and specifying those colors. Colors may be specified as an RGB triplet or in hexadecimal format (a hex triplet). They may also be specified according to their common English names in some cases. Often a color tool or other graphics software is used to generate color values. In some uses, hexadecimal color codes are specified with notation using a leading number sign (#).

A color is specified according to the intensity of its red, green and blue components, each represented by eight bits. Thus, there are 24 bits used to specify a web color, and 16,777,216 colors that may be so selected. When you combine the 3 colors, you get a specific variant. It is the same concept as mixing paint together.

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.

Below is a HTML color code pickers:
To use this widget, use the mouse to hover over the color combination that you would like to use. From there, it will generate a 6 digit/alpha # to represent the hexadecimal value of the color. A hex triplet is a six-digit, three-byte hexadecimal number used in HTML, CSS, SVG, and other computing applications, to represent colors. The bytes represent the red, green and blue components of the color. One byte represents a number in the range 00 to FF (in hexadecimal notation), or 0 to 255 in decimal notation. This represents the least (0) to the most (255) intensity of each of the color components.

Thus web colors specify colors in the Truecolor (24-bit RGB) color scheme. The hex triplet is formed by concatenating three bytes in hexadecimal notation, in the following order:

Red - 0 to 255 (0 to FF Hex)
Green - 0 to 255 (0 to FF Hex)
Blue - 0 to 255 (0 to FF Hex)
