To remove Colon from label for form elements just add this below code in to your template.php of the active theme. And replace Theme with your theme name. You can find Original code at includes/form.inc

 
function theme_form_element($element, $value) {
  // This is also used in the installer, pre-database setup.
  $t = get_t();

  $output = '

  if (!empty($element['#id'])) {
    $output .= ' id="'. $element['#id'] .'-wrapper"';
  }
  $output .= ">\n";
  $required = !empty($element['#required']) ? '*' : '';

  if (!empty($element['#title'])) {
    $title = $element['#title'];
    if (!empty($element['#id'])) {
      $output .= ' '. $t('!title !required', array('!title' => filter_xss_admin($title), '!required' => $required)) ."\n";
    }
    else {
      $output .= ' '. $t('!title !required', array('!title' => filter_xss_admin($title), '!required' => $required)) ."\n";
    }
  }

  $output .= " $value\n";
