You will have to use Notepad++ and edit the style (near the top of the document, use ctrl+f to find it). There you should remove .country{fill:#ffff80} and/or other classes as you please. Otherwise the SVG itself will continue to choose the colour for you. And don't forget to open the document in Inkscape afterwards to turn the paths grey and or check to make sure everything is the right colour. Hope that helps!
Right click on the file and it will give you options for which programme you would like to open the file with (whether or not you want to use Inkscape or Notepad++).
