Tea, whether loose-leaf, or in tea bags, loses its flavor slowly over time, and in some rare cases, can spoil or develop "off" qualities in the aroma or flavor. The rate at which this happens depends on how the tea is stored, and what variety it is. Many tea retailers overstate the degree to which tea loses its flavor, because they have an interest in continually selling their product. Most stale tea becomes somewhat bland but is still perfectly drinkable.
The aroma chemicals in tea are volatile and will escape into the air if the tea is not stored in an airtight container. For most teas, then, it is best to store the tea in an airtight container. The tea must be completely dry, or else it can mold, causing the tea to spoil.
Tea should also be stored away from light. The best way to accomplish this is to store the tea in metal tins. If you store your tea in glass jars or other containers that let light through, keep them in a closed cupboard.
One exception to these recommendations are aged teas or teas that you plan on aging. These include Pu-erh tea, and a few other types of tea. These teas are generally stored in a porous container, like a ceramic jar, in a dark, dry area away from other smells or aromas. They have active bacterial and mold cultures that enhance the quality of the tea if it is stored properly.
Tea can be brewed (loose leaf and tea bag) and there is also instant tea available. Coffee may also be brewed or instant.
Of you use 'expired' tea bags, nothing should happen food safety-wise. Any expiration date would be related to best flavor, not foodborne illness issues. Tea loses flavor as it ages. If you use old tea, the flavor might not be what you were expecting.

Actually there are a couple of blue teas available, although rare. BlueChai is one tea that when brewed is actually a nice dark blue color. It is brewed from dried butterfly pea flowers.
