SuperFish box color for second-level menu items stays black

Thank you very much for the theme.

I have successfully changed the colors of SuperFish menu by using custom images, but having hard time changing the box color for the second-level menu items from the default black.

Hovering over the second level items changes its color correctly, but the default color is black.

I have changed the hex color codes in lines 230 - 234 in the /sites/all/themes/pixture_reloaded/style.css file from the original #000, but the second level menu items backgrounds are still showing black.

#superfish-inner .menu li li {
  background: #96aaa2;
}
#superfish-inner .menu li li li {
  background: #96aaa2;

I have cleared cached data in Drupal and in the browsers.

Can you please point me in the right direction.
