Qtree ticked checkbox color

[catch]

It would really help me out to know if there is some way to colorize the checkbox inputs differently. I was able to add template with a custom header, but there are two checkboxes now (when the ticked prop is enabled and without it it does not help me), and the qtree control-color prop would colorize all checkboxes with the same color. Is there some way to loop through the child components and set the color based on node value or something like that?
Thanks in advance for any tips.
