How to change CSS colors in classical Drupal7 theme?

Question

I want to change a color of the main menu background in classical free Drupal 7 theme. It is in orange, I want to make it in the other color (dark blue or green). This is the Drupal repository for the themes

I could not locate the necessary CSS code block to change. I have read theme guides, color schemes and books on it, not clear yet. The orange color there starts with ff...

Please advise how to do it.

Here is the CSS original code:

@font-face {
  font-family: 'BebasNeueRegular';
  src: url('fonts/BebasNeue-webfont.eot');
  src: url('fonts/BebasNeue-webfont.eot?#iefix') format('embedded-opentype'),
     url('fonts/BebasNeue-webfont.woff') format('woff'),
     url('fonts/BebasNeue-webfont.ttf') format('truetype'),
     url('fonts/BebasNeue-webfont.svg#BebasNeueRegular') format('svg');
  font-weight: normal;
  font-style: normal;

}

@font-face {
  font-family: 'YanoneKaffeesatzRegular';
  src: url('fonts/YanoneKaffeesatz-Regular-webfont.eot');
  src: url('fonts/YanoneKaffeesatz-Regular-webfont.eot?#iefix') format('embedded-opentype'),
     url('fonts/YanoneKaffeesatz-Regular-webfont.woff') format('woff'),
     url('fonts/YanoneKaffeesatz-Regular-webfont.ttf') format('truetype'),
     url('fonts/YanoneKaffeesatz-Regular-webfont.svg#YanoneKaffeesatzRegular') format('svg');
  font-weight: normal;
  font-style: normal;

}
