Generating Colors in HTML


Named Colors
These 16 colors can be specified by name in HTML 4. The color names are case sensitive. So, for example, you could use either "#000000" or "Black" to refer to the color black.
Name Aqua Black Blue Fuchsia Gray Green Lime Maroon
RGB #00FFFF #000000 #0000FF #FF00FF #808080 #008000 #00FF00 #800000

Name Navy Olive Purple Red Silver Teal White Yellow
RGB #000080 #808000 #800080 #FF0000 #C0C0C0 #008080 #FFFFFF #FFFF00

RGB Hexadecimal Coded Colors

Colors may also be specified by six-character codes representing their relative red/green/blue (RGB) values, where the possible values for each color component are 00 to FF. 00 represent the least amount of the color present and FF represents the most of that color present. The first two bytes indicate the amount of red, the second two bytes represent the amount of green and the last two bytes represent the amount of blue.
Hex Value
Red Green Blue
00 00 00
Here are some simple examples:
  • Red = #FF0000
  • Green = #00FF00
  • Blue = #0000FF
  • Cyan (blue and green) = #00FFFF
  • Magenta (red and blue) = #FF00FF
  • Yellow (red and green) = #FFFF00
The number of possible colors represented by this system is 256 * 256 * 256 = 16.777,216
The six charts below display the 216 possible colors in the Netscape/MSIE palette with their hexadecimal RGB codes (a seventh chart displays the gray scale). In each chart the blue value is constant, the vertical axis represents increasing red values, and the horizontal axis represents increasing green values.
The six charts can be visualized as a cube composed of 216 cubelets; the total cube has six layers of thirty-six cubelets; each cubelet is a unique color. Using this metaphor, black (#000000) in the lower left of the first chart is one corner of the cube and white (#ffffff) in the upper right of the last chart is the opposite corner of the cube; the cubelets running through the body of the cube in a line from black to white comprise the gray scale.

HTML Attributes to Specify Color

If one of the following <BODY> attributes is used, they all should be specified in order to avoid color conflicts; for example, you may assign a backgound color and a visitor may have his/her browser set to display text in the same color, making your page unreadable. All these attributes should be specified in a single <BODY> tag.
<BODY BGCOLOR="#ff6600">
sets the background color for the page as a whole.
<BODY TEXT="#ff6600">
sets the text color for the page as a whole.
<BODY LINK="#ff6600">
sets the unvisited link color for the page as a whole.
<BODY VLINK="#ff6600">
sets the visited link color for the page as a whole.
<BODY ALINK="#ff6600">
sets the activated link color (i.e. the color of the link as users click on it) for the page as a whole.
<FONT COLOR="#cc6600">sample text</FONT>
sets the color of selected text within a page.
Although the following attributes are not included in the HTML 3.2 specification for <TABLE>, <TH>, and <TD> elements, they are included in the HTML 4.0 proposal and have been supported by Netscape since version 3.0 and by Internet Explorer since version 2.0.
<TABLE BGCOLOR="#ff6600">
sets the background color for an entire table.
<TH BGCOLOR="#ff6600">
sets the background color for one header cell within a table.
<TD BGCOLOR="#ff6600">
sets the background color for one data cell within a table.
