fluxbox styles (aka ‘themes’) are configured independent of any other environmental components.
apropos fluxbox
will list the multiple manpages related to fluxbox, and the styling howto is provided in
man fluxbox-style
To view the result when making incremental edits to a style, you don’t need to logout/in ~~ can just issue a Reconfigure command (a desktop menu entry is provided for this).
