I have pink hair, but I want bright red now?

I've had pink in my hair for a while now. It's a light pink now and my roots are showing. I want bright red hair like Hayley Williams from Paramore. I'm going to bleach my hair of course to get the pink out, but it get that kind of red what color should I use? This is the color I want or something close to this. ---> http://your-hairstyles.com/wp-content/uploads/2009/09/hayley-williams1.jpg
