Nicolai, thanks for your feedback on my question but... please let me explain further.

You know the way you can have your calendar 'shared' with someonelse.

In Google Calendar you might have, let's say, two calendars: yours, the main one in blue and another one, the shared one, coloured in pink.

As you sugested you can define new calendars using 'Settings' and you can define there their colours and visibility but I remind you that only N900 would be marked with 'syncronised' and the rest would be 'Local' type calendars.

As you know, in Erminig-NG you can define how many 'calendar profiles' you want. i.e: two calendar google accounts from/to where you can syncronise your calendar.

Apologies, maybe this would be a question more for Erminig-NG developers (I will put it there too):

how we can associate different colours to different calendars syncronised to/from two calendar google accounts? It would make more sense to have differentiate them using different colours in Home Calendar Widget, as Google is doing it

Enjoy the weekend,
Stefan
