Is this a good beginning?

I am doing a creative writing project for my Literature class. My project is an analysis of the treatment of individualism in the novella "Anthem," and consequently I'm writing a piece that should be read as a dystopian story.

This is the beginning:

---

Light.

She squints in a desperate attempt to get her bearings.

The world finally focuses, but it’s hardly better than the blinding light. Everything is white. Shadows and corners wash out in the harsh glare; the room seems endless, inescapable. If she couldn’t feel the floor beneath her feet she’d have a difficult time believing that there even was one.

She is bound to a chair. She knows this even though she cannot look down to check. The ropes are biting into her skin; her hands are cold. She imagines them turning purple and the thought allows her to slow her breathing. The drumbeat in her ears decrescendos, mezzo forte rather than fortissimo.

Movement out of the corner of her eye, and then a colorless man with a colorless clipboard comes to a halt in front of her. He leans forward.

“Alethea 4242.” His voice is sharp, words clipped. Alethea flinches away from the shards of sound. Her head hurts.

“Where am I?” she asks. A hint of panic colors her tone, but it shrivels in the endless white void.

“You are being brought to justice.” Annoyance surges up through her diaphragm to swirl dangerously in her chest. He didn’t answer her question.

Is this a good beginning? I'm not sure whether it's compelling or if the 'hostage in a white room' trope is too tired to allow for a good start to the story. Additionally, I'm not sure whether the color imagery is effective or just stupid and cliched. I'm planning to use color as a motif; color represents the individualism that Alethea champions through her otherness, while colorlessness represents the oppression of the totalitarian collectivist society in which she lives. (Music terminology may also be used, or it may be edited out.) Are these motifs too obvious or does their clarity add to the reading experience?

Additionally, how is the style in this excerpt? I'm trying for something that feels a little bit like stream of consciousness, but with more clarity. Does it work? And is the writing itself actually good? I know that it's a little abrupt, and I'm hoping to work that out in editing. (Any suggestions as to how I could do that would be much appreciated, though.)

I'm incredibly nervous about this story; I really enjoy writing, but I'm a perfectionist and I want anything that will be read by someone that I actually know to be as good as I can make it. And if I can't make it really good, then I want to know so that I can stick with a straightforward analysis and scrap my creative story.

Thank you so much to anyone who takes the time to answer my question and either confirm or put to rest my paranoid fears. Your feedback means a lot to me.
