Melinda,

I've noticed something similar, but it usually takes hours. I will
occasionally make a pot of green tea in the afternoon at work; I drink the
first infusion that afternoon, then make a second infusion and leave it till
the next morning. Even after reheating it in a microwave I notice that the
color usually has darkened and the flavor has changed. In some cases it
seems more "oolong-like", and I attributed the change to slow oxidation
overnight.

Some teas seem to benefit from this treatment - I've had Darjeelings that I
thought improved the second day. Others, like very fresh greens, seem to
lose their brightness (no surprise, I guess). Most black teas seem to show
little discernable change, which favors the slow-oxidation theory.

Regards,
Dean
