Desperately seeking decent Calendar plugin

Looking for a Calendar plugin that: allows multiple administrators; allows recurring events; allows event and/or user color-coding; supports insertion into a page and fills the width & height of the page (do not care for utilization in a sidebar widget); is compatible with Artisteer-generated themes (I’ve searched and searched and cannot find any WP themes that have the look I seek). This is for a family website that is hosted by a hosting service (not WP). As part of that service, I have Fantistico Deluxe which includes WebCalendar. WebCalendar does not provide my preferred requirements. After spending more than a week researching and trying various plugins, the closest one I have found is “Calendar” by Kieran O’Shea. However, that plugin is not compatible with Artisteer-generated themes. I have tried embedding from a Google Calendar. However, there are 2 issues with Google Calendar (1) I don’t want to make the Calendar public and (2) only way to color-code is to make a calendar for each user/event, but you can only embed or link one calendar at a time. Yahoo’s Calendar alternative also has sharing and embedding issues. Any ideas/suggestions?
