I’m pale and I say choose any shade of magenta you want! When I had magenta hair, it was a very vivid shade. But my hair is naturally dark brown and I hate the way I look with blonde/super pale hair if that says anything. Generally, pale people look better with light hair. But other factors play into this, such as your undertones and your features. In short, if you're pale and naturally have dark hair, then dye your hair a deep magenta. I have dark features (brown eyes, dark eyebrows, etc.) so light hair colors wash me out.
