I am creating a transition slide with only one number sign #

The single-hash slides are slide.dark and the main font of these slides is the h2 group, so you need something like this in your .css:

slides > slide.dark > hgroup h2 {
  color: #FFFFBB;
  font-size: 72px;
  letter-spacing: 10;
}

Other elements of this slide like background can be customized with

slides > slide.dark {
  background: none !important;
  background-color: #444444 !important;
}
