I know there is a bug in bugzilla for this, but I want to know how I can add colors manually.

I located some color configuration in /jetty/webapps/zimbra/js/Startup1_2_all.js

Is this the correct location for the calendar colors?

When I've edited the .js file, how do I then generate the .zgz file ?

I tried it with gzip -cN Startup1_2_all.js > Startup1_2_all.js.zgz

But after reloading and trying to open the properties dialog I get: D is undefined.

Someone an idea on this?
