styling kwicks

I have a 4-item menu for which i have created a kwick. I need a little assistance with styling the kwick menu. I have written some basic CSS (pasted below), however I'm far from my objective, which is to come as close as possible to this example.

#kwicks-0-kwick0 {
  background-color: #60FF60;
}

#kwicks-0-kwick1 {
  background-color: #C9693C;
}

#kwicks-0-kwick2 {
  background-color: #DD4953;
}

#kwicks-0-kwick3 {
  background-color: #DD5C06;
}

ul.kwicks li {
  background: none;
}

would appreciate some assistance with this...
