MM ---- thanks for posting those other photos. From the looks of those other photos, the colour of the leaves look quite good.
If you just allow for a dry-out (gentle air-movement around the leaves and stem), and soak only the root section - which is what you mentioned you are going to do already ------- then your orchid will likely be just fine. Just maintain suitable temperature for the orchid.
The black edging should be ok. If it just stays like that, and dried up, then it will be ok
