Solved! How can I change this color

[Schnuffel2008]

Hi,
is there a way to change the color for the element in the attached screenshot for my my own skin? It is to dark and can't be seen.

PS: I found the solution on my own. You have to add the following lines in the main.css:

ul.jqtree-tree .jqtree-toggler {
 color: #XXXXXX !important; }
