They haven't changed on mine, still green. it's probably your app which is doing it. The aggregators are nothing to do with Q they just gather his posts from 8kun and the various colours on the IDs are more to do with the way the aggregator works I think.

If you click on the post number where it's cross-posted to the 8kun research board you'll see there is no colour labels at all. (Don't go posting on there as a noob though, they don't like it and they can be rather offensive - it is an offspring of the chans and pol after all. If you aren't used to that environment best to stay away and just read the aggregated posts. :)

newbies... Q is a group of 10, both military and civi...i would assume the color codes are more an identifier as to whom actually posted the drop. IMHO

Be prepared for red I guess

Mine are always like that, on PC, windows, Waterfox...

Relevant?

I mean the actual color of the number,hope it means something good.

Post # (e.g. 3570) colors indicate when a post was made. It makes it easier to see which posts were made today, yesterday, etc. Today Yesterday 2 Days 3 Days 4 Days 5 Days 6 Days etc.

Color is now sort of green.Day before red

I noticed that myself on Qalerts.app. I figure it has to be something, I just have no idea what.
