Colors in floor plan/section semi-detached house

Hello everyone,

what is the meaning of the colors in the floor plan/section: green/red? It is a solid semi-detached house built in 1993.

See pictures (the topic of the wooden balcony brought us to the question)

Thank you very much
Fabian

Presumably:
Green walls = structurally necessary.

Or in timber frame construction:
Green = wood
Red = masonry or drywall

Show everything and not just a part - it's like a puzzle…

presumably:
Green walls = statically necessary.

I have not yet been able to identify fixed conventions of color assignment in practice, let alone encode a distinction based on static relevance. What I often see is a distinction between masonry (often: red), (reinforced) concrete (often: light green), and lightweight construction (occasionally: blue).

Or in timber frame construction:
Green = wood
Red = masonry or drywall

I believe that even less here.

In our plans, dashed lines represent concrete, hatched ones represent calcium silicate brick, and load-bearing walls are in red. You can find all this in the legend of the plan by the way :p

In our plans, dashed is concrete, hatched is sand-lime brick, and load-bearing walls are in red.

So sand-lime brick load-bearing then hatched and red?

By the way, you can find everything in the legend on the plan :p

Oh yes, legends – unfortunately, they seem to have gone out of fashion like signaling before turning.
