Jumpringer99 on "Make a page title in two colors"

I want page titles of three specific pages to display two colors.

The solution may be a php statement replacing a string with css.

I've tried this several times with no luck... for example:

<?php
$myPageTitle = get_page(244));
$myPageTitle = str_replace(array('...that', '<span>...this</span>'), '', $myPageTitle);?>
<?php echo $myPageTitle; ?>

Suggestions welcome....thanks.
