They do get into that color when growing far too long, compacted in bark media. Still looks hopeful to me, leaves seems still green and good. The thread like things is actually the real root with no velamen protection.
Did this plant bloom recently? It maybe in rest mode though, so be very careful it does not stay too soaking wet in whatever media you use.
