Choosing a color before a major haircut

I am in a small theatre production next month, and the costume designer suggested face-framing bangs for my character. I like the shape in the costume sketch, but I have to pin my hair up between scenes, sometimes in less than two minutes. Several scenes involve quick turns and movement. A fringe that falls into my eyes would be distracting, particularly with bright lights facing the audience. I need to see my marks clearly through each scene. My hair is fine and mostly straight, so I cannot count on a styled bend staying in place for the whole performance. I found curtain bang lengths helpful for naming the options, but I need to decide where the shortest pieces should actually end. Would a longer fringe be easier to pin back quickly? I can rehearse with clips before cutting anything, although the final costume headpiece may change how the hair sits. A rehearsal should show whether the clips stay secure. I would also like the cut to work offstage. I would rather adjust the styling than spend every scene fixing loose strands. Has anyone dealt with bangs during quick costume changes? What length gave you a useful frame without blocking your view?
