Is it possible to obtain Yellow or Blue Brewfest Stein?

[Smoorfz]

From the brewfest event I do have the Green Brewfest Stein, I don't even remeber how I got it though, got the achievement in 2021.
Does anyone know if every year you can obtain a different one from the event or it's always the same (Green)?

You get the green one because you are doing the 2009-2010 version of the quest. https://wowpedia.fandom.com/wiki/Brewfest_Stein

I got yellow and green achieved on my lock Vladyr - on the same day but I don't recover anything from then, it was 2015
