Web colors Web colors are colors used in displaying web pages, and the methods for describing 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. Hex triplet[edit] A hex triplet is a six-digit, three-byte hexadecimal number used in HTML, CSS, SVG, and other computing applications, to represent colors. Byte 1: red value (color type red) Byte 2: green value (color type green) Byte 3: blue value (color type blue) For example, consider the color where the red/green/blue values are decimal numbers: red=36, green=104, blue=160 (a greyish-blue color). Note that if any one of the three color values is less than 16 (decimal) or 10 (hex), it must be represented with a leading zero so that the triplet always has exactly six digits. The number of colors that can be represented by this system is 2563 or 224 = 16,777,216. Shorthand hexadecimal form[edit] X11 color names[edit]
Color Numbers - Hexadecimal Colour Value Calculator for HTML Use this simple java applet to compare html colours quickly and easily. Excellent for designing web pages, as you can set the foreground and background colors to your tastes, and then read their hexadecimal "color code" values, which are used in HTML. You can contrast different sizes of text and/or a big colored area against the background colour. Note that the colours shown are java's interpretation of the colour value. I have chosen a non-descript gray colour for the background of this page, so that your eye may experience the colours you choose with a 'clean palette', as it were. As a note of interest, on page 13 of IBM's G40 Monitor Handbook, 'IBM recommends that the use of primary colour blue on a dark background be avoided. If you bookmark this page, you can come back and use this powerful tool any time you feel like. If you wonder why I consistently spell color/colour as color or colour, it is because I don't trust the search engines to find you one if you search for the other.
List of colors The following is a list of colors. A number of the color swatches below are taken from domain-specific naming schemes such as X11 or HTML4. RGB values are given for each swatch because such standards are defined in terms of the sRGB color space. It is not possible to accurately convert many of these swatches to CMYK values because of the differing gamuts of the two spaces, but the color management systems built into operating systems and image editing software attempt such conversions as accurately as possible. The HSV (hue, saturation, value) color space values, also known as HSB (hue, saturation, brightness), and the hex triplets (for HTML web colors) are also given in the following table.
