Hi Mueschel,
at https://www.openstreetmap.org/node/11022143425 you changed 
...
recycling:brown_bottles=yes
recycling:brown_jars=yes
...
to
recycling:glass:colour=brown
recycling:glass_bottles=yes
recycling:glass_bottles:colour=brown
recycling:jars=yes

recycling:glass:colour=brown was not originally mentioned and seems to have been written by mistake.
It should consequently read recycling:glass_jars:colour=brown, because nothing was previously written about the color of the recycled glass.

Regards
lyctkel
