I have noticed the same thing with my Vandas. If you rub the old part when
wet it seems to green up quicker. Is there a protective coating on the
older part of the root?

I just returned from a business trip, so sorry if this is late, but I have
a vanda in the GH that is totally unpotted, hanging from a wire.

The roots that grew last year sort of stopped over the winter. This
spring they all stated to branch like crazy. The "old part" greens up
rapidly when sprayed, the new growth does not.

From that, what do we speculate?

Someone in our local society mentioned that the water temperature can
have a big effect on how quickly the roots turn green. He said warmer
water turns them green faster.
