Customizing Themes

[Id]

Hey folks!

I'm trying to customize some look and feel of gwt-cal.
Right now I'm using Google theme style and I want to change the aspect of the appointments.

Here what I need:
- Change the color of header/body apointment from #fff to another HEX value defined by me;
- Change the appointment header background to a RGBA value defined by me;

Right now, changing the gwt-cal-google.css I already customize the border-radius and some minors aspects but I stil can't change those how I mentioned above.
I was trying to find/edit some style information at the AgoogleAppointmentStyle.class but looks like I just can see this file but not edit it...

Well, let me show you what I have and to what I need (Just link's to .png's hosted in CloudApp):
What I have today: http://cl.ly/0J3K0k2b1U2v2R3L1k2V
What I want to have: http://cl.ly/0c08202m1Z2t3P3d313j

I will appreciate if one of you can help me. :)
Thanks!

The themes are defined here:

http://code.google.com/p/gwt-cal/source/browse/trunk/gwt-cal/src/main/java/com/bradrydzewski/gwt/calendar/theme/google/client/GoogleAppointmentTheme.java

You have the option to create your own theme (similar to what we did for Google theme, Apple theme, etc), or you can just modify the GoogleTheme and re-compile
