You can do this in 2.0.9:

  * It is now possible to specify a label for lines in the plot key
    when using the plot function.  For example,

      plot (x, y, "-*;sin(x);")

    plots y vs. x using the linespoints style and sets the title of
    the line in the key to be `sin(x)'

To tell gnuplot's postscript terminal driver to use color, try

  gset terminal postscript color
