I'm guessing you live in the northern hemisphere. Many pitcher
plants which are normally green or green with some red during spring
and summer develop a deep red color this time of year. It has to do
with fall coming in and is similar to what you see happening to tree
leaves. I suspect the red coming out is due the decrease in the
amount of green chlorophyll, allowing red (anthocyanins) to show
through.
For the Sarracenia in my outdoor bogs here in Atlanta, S. alata is
the most obvious for this phenomenon.
