To make the picture even more strange, if I preview the destination folder at the time the message arrives (via regular polling, not via the 'check your pop3..." button because this will change the previewed folder) then I am able to scroll through the folder and see the new message appear WITH the associated colour. If, however, I preview another folder and return to target folder, the colour is gone.

Your second paragraph (quoted above) quite clearly indicates an issue. Your filter is obviously working as intended - the problem is that the message property of colour is somehow lost/forgotten.
I've not really used public folders but you state that you have global attributes, so that destroyed my first idea. That said, if you've got so many public folders, it might be worth double-checking that this particular folder IS set to global attributes (and that you didn't lose concentration when setting them all up!).
My next thought was that perhaps the permissions on the drive share are interfering but I can't see how the colour would be reset but the message could be copied with no other issues. Can't be that then.
Apologies if this is what Steffan was alluding to, but can you perhaps work around the issue by moving the message-colouring part of the filter into a general folder-open filter applied to the public folder? This splitting of the two functions in your process may be a few minutes of awkwardness for you but it will at least allow us to perceive whether the problem lies in the concatenation of the tasks within one filter or, if the problem persists, that there may be some wider issue regarding colouring in public folders.
You could also use such a general rule set to test whether it is only this one particular public folder that has the issue or many/all. That information might also be useful in resolving the problem.
