I deleted the scroller.setForeground(...) and 
scroller.setBackground(...) statements, since they did not have any 
effect, and added your statements before

JScrollPane scroller = new JScrollPane(...

Well, they were partially effective, I mean the second was effective, 
the background did change to the color I specified, but the foreground, 
that is the scroller itself, did not change from what it was before.

Why?
