My friend is interested in starting up photography and asked to borrow one of my film cameras (my Minolta X-570) as a start. She just developed her first roll, and while a few photos look okay/correct color, many look like one of these two in terms of color, where everything looks either too tan or too blue/cold:

My theory is that the two photos are underexposed and the lights that they were in made the photos turn out either tan or blue. Is this a correct theory, or is there something else causing this? For reference, the film is Kodak 400.
