Create colors for recycling based on recycling tag

[matthijsmelissen]

Mapnik could render the recycling bins in 3 different colors:

• green for glass
• blue for paper
• yellow for plastic, metal,etc

based on the recycling tag.

these colors are the color codes in Germany. So i am not sure if the colors are globally understood.
If there is no other color schema the german version should be used.

iirc the recycling tag is not available, so we have to wait for a database rebuild.

Internationally this will be different so I am not sure we can do this sensibly anyway even if we wanted to by added it in 3.x
I would close it.

IMHO almost certainly it is too much of clutter, I would close it without rejecting potential future request.

fwiw, here at the curbside, it's green for organics, blue for plastic/paper/metal, and black for waste.

Wikipedia shows

• glass and plastic bottles as red, cans as yellow and paper as blue in Singapore
• Food as green, general waste as black, paper as blue, plastics as orange
• Brown glass as brown, green glass as green, paper as red, and blue for something illegible
• Green for paper, blue for cans and bottles, black for waste

Following some of the links, I also see

• Green for food, blue for paper, red for plastic bottles
• Gray for paper, blue for canns and bottles, black for waste
• Yellow for bottles and cans, blue for paper, gray for waste
• Blue for paper, aqua for mixed glass, red for plastic, black for waste
• Green for bottles and cans

Given the lack of a standard colour coding, I can't see any way to indicate different materials that will convey meaning internationally.
