[Feature Request] different icon color for saved unread and saved archived pages

[brabalan]

I use Wallabag to store pages to read later and to remember the ones I have already read. It would be useful to have a different icon color for pages saved in Wallabag that are archived (hence for me already read). I know I can press on the icon to see the status of the page (unread or archived), but sometimes this puts an archived page back to unread.
