The Sokol is a Russian rescue suit that continues to be used today$^{(1)}$ for launch and landing. It protects the wearer from depressurization, but because it has no micrometeroid and limited thermal protection, it is not rated for EVA use.
As you can see in the picture, the Sokol is white. This is in contrast with the equivalent American suits (LES and ACES), which are both safety orange. Considering that Soyuz lands on land -- which may have snow cover -- one would expect safety orange to be more visible than white.
Is there an official reason why the Sokol is white?
$^{(1)}$ "Used today" ignoring the temporary grounding of Soyuz flights.
