S12 Color Code Table

Sweden's own take on the color code — a Telia-era standard that stuck around, so it shows up a lot here. Tube and fiber position both follow the same 12-color sequence below, but there are two documented tube-marking schemes: the full cycle, or a sparse version where only the first two tubes are colored and the rest are unmarked white (see note below). Note: ducts follow a completely different 7-color sequence — no relation to the tube or fiber order, so don't try to cross-reference them.

Color order (tube & fiber): Red Blue White Green Yellow Grey Brown Black Purple Orange Aqua Pink
Sparse tube scheme: Tube 1 Red Tube 2 Blue Tube 3–16 White (trace by position, not color)
Duct order (unrelated to tube/fiber): Orange Yellow Red White Grey Purple Blue
