CodeColorer is the plugin which allows you to insert code snippets into the post with nice syntax highlighting.
Plugin based on GeSHi library, which supports most languages. CodeColorer has various nice features:
<ul>
<li>syntax highlighting in RSS feeds</li>
<li>syntax highlighting of a single line of code (inline)</li>
<li>syntax highlighting of code in comments</li>
<li>line numbers</li>
<li>automatic links to the documentation inserting</li>
<li>code block intelligent scroll detection (short code would have a short block, for a long one the block height would be fixed and a scrollbar would appear)</li>
<li>predefined color themes (Slush & Poppies, Blackboard, Dawn, Mac Classic, Twitlight, Vibrant Ink, Railscasts, Solarized Light, Solarized Dark)</li>
<li>syntax colors customization in CSS file</li>
<li>code protect from mangling by WordPress (for example, quotes, double-dashes, and others would look just right as you entered)</li>
</ul>

Syntax coloring is highly customizable: you could change the color scheme for all languages or a specific language. You could find CodeColorer CSS in wp-content/plugins/codecolorer/codecolorer.css file. To change colors for all languages edit lines below Color scheme section.
There is simple mapping exists between Textmate color themes and CodeColorer ones:
<pre><code>/* "Slush & Poppies" color scheme (default) */
.codecolorer-container, .codecolorer { color: #000000; background-color: #F1F1F1; }
/* Comment */
.codecolorer .co0, .codecolorer .co1, .codecolorer .co2, .codecolorer .co3, .codecolorer .co4, .codecolorer .coMULTI { color: #406040; font-style: italic; }
/* Constant */
.codecolorer .nu0, .codecolorer .re3 { color: #0080A0; }
/* String */
.codecolorer .st0, .codecolorer .st_h, .codecolorer .es0, .codecolorer .es1 { color: #C03030; }
/* Entity */
.codecolorer .me1, .codecolorer .me2 { color: #0080FF; }
/* Keyword */
.codecolorer .kw1, .codecolorer .kw2, .codecolorer .sy1 { color: #2060A0; }
/* Storage */
.codecolorer .kw3, .codecolorer .kw4, .codecolorer .kw5, .codecolorer .re2 { color: #008080; }
/* Variable */
.codecolorer .re0, .codecolorer .re1 { color: #A08000; }
/* Global color */
.codecolorer .br0, .codecolorer .sy0 { color: #000000; }
</code></pre>
