The Coloring tool can be used to query information about colors and classes as well as for installing a private colortable into a project. Installing a private colortable (by adding a color) is highly discouraged without a deep understanding about how coloring of elements is handled.

If a private colortable is installed into a project, it resides in the file called "colordefs.xml" in the projects folder. This file is loaded everytime, the project is (re)loaded and will override default colortable of the nenya resource. The XML file can be deleted or edited by hand anytime.
