I can't get my calendar to look like the one shown with the Lightning 0.9 down load.

I have recently started using the google Thunderbird, primarily the calander. I assume the calendar is the lightening add on, but mine doesn't look like the picture that is with the Lightning 0.9 download. I can't get the color for the appoints as shown in the picture and I don't get the spacing as shown in the picture. What am I missing?
