<h2>Color Values</h2>
<p>CSS colors can be defined as a hexadecimal notation for the combination of Red, Green, and Blue
color values (RGB).</p>
<p>The lowest value that can be given to one light source is 0 (hex #00) and the highest value is 255 (hex #FF).</p>
<p>The table below shows the result of combining Red, Green, and Blue light
sources:</p>

<h2>W3C Standard Color Names</h2>
<p>W3C has listed 16 color names that will validate with a CSS validator.</p>
<p>The color names are: aqua, black, blue, fuchsia, gray, green, lime, maroon,
navy, olive, purple, red, silver, teal, white, and yellow.</p>
<hr />
<h2>Cross-browser Color Names</h2>
<p>A collection of nearly 150 color names are supported by all major
browsers.</p>
<p><a href="css_colornames.asp">View the cross-browser color names</a></p>
<hr />
<h2>Cross-browser Color Values</h2>
<p>Some years ago, when most computers only supported 256 different colors, a
list of 216 Web Safe Colors was suggested as a Web standard. The reason for this
was that the Microsoft and Mac operating system used 40 different
"reserved" fixed system colors (about 20 each).
</p>
<p>We are not sure how important this is now, since most computers today have the ability to display millions of different colors, but the choice is
left to you.
</p>
<p>The 216 cross-browser color palette was created to ensure that all
computers would display the colors correctly when running a 256 color palette:</p>
