If I set CSSOnly to False, I can change the background colours of the events dynamically on the beforeEventRender property, but when I use CSS themes (which do look a lot better than the default), the theme overrides the event backgroundcolour and I can't do this any more. Is there a middle ground. I'm trying to render the events as different colours depending on a rule so that the user can immediately view event statuses as colours. I've tried using a CSS prefix and setting CSSOnly to False, but that just comes out as the default look again. Help.
