From the help of the Navigator module:
The node object:
Each nav template is provided with an array of node objects that match the criteria specified on the tag. Below is a description of the members of the node object:
$node->id -- The content object integer ID.
$node->type -- The type of the node. i.e: content, link, pagelink, etc.
$node->url -- URL to the content object. This should be used when building links.
$node->accesskey -- Access Key, if defined.
$node->tabindex -- Tab index, if defined.
$node->titleattribute -- Description, or Title attribute (title), if defined.
$node->hierarchy -- Hierarchy position. (i.e. 1.3.3)
$node->default -- TRUE if this node refers to the default content object.
$node->menutext -- Menu Text
$node->raw_menutext -- Menu Text without having html entities converted
$node->alias -- Page alias
$node->extra1 -- This field contains the value of the extra1 page property, unless the loadprops-parameter is set to NOT load the properties.
$node->extra2 -- This field contains the value of the extra2 page property, unless the loadprops-parameter is set to NOT load the properties.
$node->extra3 -- This field contains the value of the extra3 page property, unless the loadprops-parameter is set to NOT load the properties.
$node->image -- This field contains the value of the image page property (if non empty), unless the loadprops-parameter is set to NOT load the properties.
$node->thumbnail -- This field contains the value of the thumbnail page property (if non empty), unless the loadprops-parameter is set to NOT load the properties.
$node->target -- This field contains Target for the link (if non empty), unless the loadprops-parameter is set to NOT load the properties.
$node->created -- Item creation date
$node->modified -- Item modified date
$node->parent -- TRUE if this node is a parent of the currently selected page
$node->current -- TRUE if this node is the currently selected page
$node->children_exist -- TRUE if this node has any children at all.
$node->children -- An array of node objects representing the displayable children of this node. Not set if node does not have children to display.
$node->has_children -- TRUE if this node has any children that could be displayed but are not being displayed due to other filtering parameters (number of levels, etc).
(optional) loadprops="" - Use this parameter when NOT using advanced properties in your navigator template. This will disable the loading of all of the content properties for each node (such as extra1, image, thumbnail, etc.). This will dramatically decrease the number of queries required to build a navigation, and increase memory requirements, but will remove the possibility for much more advanced displays
I think that is enough to get you going. If not, don't hesitate to tell us what isn't clear.
On a side note: this module provides a color picker you can include on the page editor:
http://dev.cmsmadesimple.org/projects/ecb2
It can NOT be used together with the extra1, 2, 3 attributes but with this tag you can use the chosen values inside a Navigator template:

This would useful if editors that don't know/understand color codes need to be able to change them.
