color json not importing

Hi,
I am having trouble importing this JSON. The plugin gives a success message when I import a file containing this string, but the colors don't show up. What am I doing wrong?

{"background_color":"#37B22A","text_color":"#000000","link_color":"#8F5000","link_color_hover":"#E19A9E","link_color_visited":"#8D0007","content_text_color":"#000000","content_link_color":"#678192","content_link_hover_color":"#E19A9E","content_title_color":"#064400","header_background_color":"#0E9700","header_text_color":"#678192","site_title_color":"#678192","site_tagline_color":"#86BB80","navigation_background_color":"#678192","navigation_text_color":"#002035","navigation_background_hover_color":"#002035","navigation_text_hover_color":"#678192","navigation_background_current_color":"#03395C"}

Thanks!
Henry
