Romeo and Juliet - Just Bad Lighting? I Think Not!
In the movie, watch Juliette's eyes closely. I the first couple of scenes, her eyes are brown, then through a couple more, they are green, and then brown, and occasionally blue. Contacts, or bad lights? What's up with that???
Some people, such as my girlfriend and I, have hazel-colored eyes. Most of the time, hazel eyes change color due to that person's mood. The color fluctuates from brown, green, and even an occasional, almost, purple.
Also, many people's eyes seem to change color in different light. Mine are green but look blue if I wear blue. Under the kind of lights you have to have for a movie, where there's a lot more manipulation of color required, I assume the effect would be even more pronounced.
