I purchased this pitcher plant from a local garden center and was just curious if it looked familiar to anyone!

graciliflora x ventricosa aka "ventrata"

It does say that the ventrata lids are sometimes green but does that mean the opening of the pitcher would be green too?
This is my first pitcher plant—can the pitchers be lighter or darker depending on lighting and stuff?

Lights and other environmental conditions (even acclimation) definitely affect pitcher color. You can see some examples of mine grown inside by a window with supplemental lighting here.
