Are zebras black with white stripes or white with black stripes?

Based on scientific,zebra are white with black stripes.But the main question is that our eyes can see clearly that zebra black with white stripes or white with black stripes.For me,zebra is an unique animal because they're in horse family.Maybe we always see that people riding a horse but have you ever seen people riding a zebra?so,it is correctly if I said that zebra makes us feel that every human have their own perception when they see this animal just like their own vision in their life's.We all different but we can share our ideas to get more revolution.That's all guys...
