There is no colors keyword for iplot, that I am aware of.There is
color, which is used to set the color of the plot line by its rgb
values (a constant color, while vert_colors sets the color at each
vertex.

In IDL 7.1, you can save the current itool to isv, ps, eps, and a
bunch of other formats with

isave,'file.ps'

It guesses the format by the extension in the file name.

Before 7.1, you can, in the iplot window, go to the menu file->export-
