Hexadecimal Colors
To specify colors on the Web you must
enter the pound sign # followed by the 6 character hexadecimal
code. Here are some examples:
| #000000 |
|
#00CC00 |
|
#CC0000 |
|
| #FFFFFF |
|
#FF9900 |
|
#CC0099 |
|
| #0000CC |
|
#FFCC00 |
|
#990000 |
|
| #FF0000 |
|
#FF6633 |
|
#00FFFF |
|
| #FFFF00 |
|
#666666 |
|
#99CC00 |
|
Using HTML and hexadecimal color codes,
you can specify
- background color
- text color of the whole page
- text color of some selected text
- text color of links, viewed links and active links
- background color of table or table cell
Color is an attribute:
Body Attributes
You can specify a background color for
your HTML page, as well as text color, link color (the color
of your links before they have been clicked), viewed link
color (the color of your link after it's page has been viewed)
and active link color (the color of your link while the
link is clicked down.)
These colors are put into your HTML
page as an attribute of the body tag.
<body bgcolor="#00CC00"
text="#FFFFFF" link="#000099" vlink="#333333"
alink="#FFFF00">
This will make a green page with white
text, navy blue links that turn dark grey after being viewed,
and yellow while the link is pressed.
See
an example of this page.
Changing Text Color
Using the above body attributes to specify
color will change all of the links and text color on your
whole page. What if you just want one line or one part of
your text to be a different color?
Color is an attribute that can also
be specified inside the font tag. Notice how the font tag
is applied to each letter here. Even though all of the text
is size +7, the color of each letter changes, therefore
the font tag has to start and end after each letter, and
be re-applied for the next.

<font face="Arial, Helvetica, sans-serif" color="#FFFFFF"

<b>S</b>
</font>
<font face="Arial, Helvetica, sans-serif" color="#0000FF"

Web Safe Colors
Both Macs and PCs have 256 colors in
their system palettes, but only 216 of them are the same
colors. These 216 colors can be viewed the same on all computers.
These are called "browser safe colors" or "Web
safe colors."
Just because a color is expressed in
a hexadecimal code, this does not mean the color is Web-safe.
It's easy to recognize a web-safe color
in HTML code because all Web safe colors are a combination
of 00, 33, 66, 99, CC, and FF

how colors work)
Hexadecimal Colors and RGB Colors
Web images are created using a RGB (red
green blue) palette, as opposed to CMYK (cyan magenta yellow
black) that is used for print.
Make sure you are working in RGB color
mode. In Photoshop go to Image-->Mode and select RGB
color.
In
Photoshop, you can select color by clicking the color box
at the bottom of the toolbar (circled on left). When you
do, the color picker (below) pops up.
Notice the box on the bottom that says
Only Web Colors. Make sure this box is checked.
Notice the R, G, and B values that are
inside the red box? These 3 numbers are the "recipe"
that mixes a specific amount of red, green, and blue in
order to produce a color. The number at the bottom, #3333CC
is the hexadecimal value for this RGB color.
It is important to know the RGB value
as well as the hexadecimal code for the color if you have
to match colors on your Web page to specific colors in your
graphics.
Once you decide on colors, be consistent!
Use these codes to guarentee that you always use the same
exact color.
