Phpunit xml color setup instructions dosen't work

Question

I am defining a phpunit.xml configuration file for my unit tests. In this file, I instruct you to show colors in unit test results as follows:

<phpunit
   ... 
   colors="true"
   ... 
</phpunit>

When I run tests on the command line, everything is fine, except that I do not get green and red colors in the results.

If I delete the configuration file and use the option --color=alwayson the command line, I get a result with colors.

In the configuration file, I'm already trying to change colors="true"to colors="always"without result.

Is there a problem with my configuration file?

Here is my phpunit.xml configuration file:

<phpunit
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:noNamespaceSchemaLocation="http://schema.phpunit.de/5.1/phpunit.xsd"
  backupGlobals="true"
  backupStaticAttributes="false"
  cacheTokens="false"
  colors="true"
  convertErrorsToExceptions="true"
  convertNoticesToExceptions="true"
  convertWarningsToExceptions="true"
  forceCoversAnnotation="false"
  mapTestClassNameToCoveredClassName="false"
  printerClass="PHPUnit_TextUI_ResultPrinter"
  processIsolation="false"
  stopOnError="false"
  stopOnFailure="false"
  stopOnIncomplete="false"
  stopOnSkipped="false"
  stopOnRisky="false"
  testSuiteLoaderClass="PHPUnit_Runner_StandardTestSuiteLoader"
  timeoutForSmallTests="1"
  timeoutForMediumTests="10"
  timeoutForLargeTests="60"
  verbose="false">
 <testsuites>
   <testsuite name="examples">
     <directory>/home/miguelbgouveia/Documents/projects/joomla/tests</directory>
     <file>test_example.php</file>
   </testsuite>
 </testsuites>
</phpunit>

And the phpunit version is 5.1.2
