Do you use Maven 3? Then you can use this repository:

<repository>
	<id>ColorMe-Repo</id>
	<url>http://ci.dustplanet.de/plugin/repository/everything/</url>
</repository>

<dependency>
	<groupId>de.dustplanet</groupId>
	<artifactId>ColorMe</artifactId>
	<version>3.8-SNAPSHOT</version>
</dependency>

To use the API create a new instance of Actions. You have to use the ColorMe instance, too!
Below is a small example:

import de.dustplanet.colorme.Actions

Actions actions = new Actions((ColorMe) getServer().getPluginManager().getPlugin("ColorMe"));
actions.createGroup("APITest");

OR you use the alternate method of hooking into ColorMe:

import de.dustplanet.de.colorme.Actions

Actions actions = Actions.hookIntoColorMe();
actions.createGroup("APITest");
