All the information that google returns says to change ~/.gtkrc2.0-mine. Here is my .gtkrc-2.0:

# -- THEME AUTO-WRITTEN BY gtk-theme-switch2 DO NOT EDIT
include "/usr/share/themes/Dust/gtk-2.0/gtkrc"

include "/home/mars/.gtkrc-2.0.mine"

# -- THEME AUTO-WRITTEN BY gtk-theme-switch2 DO NOT EDIT

Here is my .gtkrc-2.0.mine:

style "default"
{
        GtkTextView::cursor_color       = "#ffffff"

        base[NORMAL]    = "#111111"
        base[ACTIVE]    = "#111181"
        base[SELECTED]  = "#808080"
        text[NORMAL]    = "#c0c0c0"
        text[ACTIVE]    = "#c0c0c0"
        text[SELECTED]  = "#111111"
}
class "GtkTextView" style "default"

Still appears with a white background!
