When a Wikimedia user gets an alert - I mean an alert at the top of the page close to the bell-sign - a red label with a number appears. This gives a shock... one might think you made a severe error, while usually somebody just pinged you, or you received a message on your talk page. I checked this with some other persons, they feel the same.
Only in some cases it is a revert..
Could the color be changed from red to green or some other friendly color?
