<p>The following table shows each of the available colors and their equivalent values in the .NET Framework, as defined in the <b>System.Drawing.KnownColor</b> enumeration. Any element with a color property ( ForeColor, BackColor, etc. ) can take one of the following values.

<div class="header"><h3>Known Colors</h3></div>

<br>
<div align="center">
<table class="colortable">
<tr>
   <th>Color</th>
   <th>Name</th>
   <th>Hex Value</th>
   <th>Red Value</th>
   <th>Green Value</th>
   <th>Blue Value</th>
</tr>
<% foreach ( KnownColor k in colors ) {
      Color c = Color.FromKnownColor ( k );
      if ( !c.IsSystemColor ) {
         string h = hex ( c ); %>
         <tr>
            <td style="width:100; background: #<%= h %>">&nbsp;</td>
            <td><%= c.Name %></td>
            <td><%= h %></td>
            <td><%= c.R %></td>
            <td><%= c.G %></td>
            <td><%= c.B %></td>
         </tr>
      <% }
   } %>
</table>
</div>

<div class="header"><h3>System Colors</h3></div>

<p>The <b>KnownColor</b> enumeration also includes the collection of system colors, which represent colors that are used in a windows display element.

<div align="center">
<table class="colortable">
<tr>
   <th>Color</th>
   <th>Name</th>
   <th>Hex Value</th>
   <th>Red Value</th>
   <th>Green Value</th>
   <th>Blue Value</th>
</tr>
<% foreach ( KnownColor k in colors ) {
      Color c = Color.FromKnownColor ( k );
      if ( c.IsSystemColor ) {
         string h = hex ( c ); %>
         <tr>
            <td style="width:100; background: <%= ColorTranslator.ToHtml ( c ) %>">&nbsp;</td>
            <td><%= c.Name %></td>
            <td><%= h %></td>
            <td><%= c.R %></td>
            <td><%= c.G %></td>
            <td><%= c.B %></td>
         </tr>
      <% }
   } %>
</table>
</div>

<p>A color in ASP.NET may be specified in several ways: 
<ul>
   <li>by passing a color name from the <b>KnownColor</b> enumeration above, ex. <b>DarkSlateGray</b>;</li>
   <li>by passing color values that denote the RGB components ( red, green, and blue ) expressed in hexadecimal format, ex. <b>#ccffaa</b>;</li>
   <li>by passing color values that denote the RGB components expressed as intensity values ( 0-255 ), ex. <b>rgb ( 240, 230, 140 )</b>.</li>
   <li>by passing color values that denote the RGB components expressed as percentages ( 0-100 ), ex. <b>rgb ( 25%, 50%, 75% )</b>;</li>
</ul>

<!-- <p>For more information on specifying colors, see <a href="colors.aspx">Colors and Backgrounds</a>.
 -->

<p>This page uses a simple <b>Enum.GetValues</b> method to retrieve the pre-defined known colors into an array. The array is then looped thru using a simple <b>foreach</b> statement, and from each <b>KnownColor</b> object a <b>Color</b> structure is created, the values of which are extracted ( and converted to hex ), and the results dynamically generated on the page.
