How to edit link colors in GTK themes

After trying several new themes today, I found out that many  gtk theme makers usually forgot to edit the link colors in their dark themes and it can be very annoying. Here are the two examples of these themes when I use firefox, the first is silent night II, the second is diehard 4. As you can see in the images, the link color combination seems to want our eyes to bleed out.

Fortunately, fixing this problem is pretty easy. You need to go to the themes folder (either /usr/share/themes/ or ~/.themes) then open the gtkrc file (in the gtk-2.0 folder) with a text editor of the theme you want to use. Just add the following lines right after the part style "default"

  GtkWidget::link-color = "#569cc1" # choose the color that you prefer   
  GtkWidget::visited-link-color = "#f2f2f2"  # choose the color that you prefer

The file should look like this

 Here are how the link colors look in the two example themes after I editted the gtkrc file. I believe it looks really better.
