I don't know anything about changing the background color in PBM --
sorry.

But you can choose the color of the line chart.

First, use the command 'test'.  This displays a lot of stuff about your
terminal (x11, pbm, postscript...), including an array of line and point
styles.  Each style is accompanied by an index. number.

You can put the index numbers for the line and point style you want at
the end of the 'plot' command.  Thus

  plot f1(x) with lines 3, f2(x) with points 0 5

will plot f1 with a line of style 3 and f2 with points of style 5
(the '0' is a dummy value for the unused lines).

The styles are different for each terminal, so what you see on your
monitor isn't necessarily what you'll see on your hardcopy.
