If your hair has never been colored before and your box dye is permanent color, then yes. If you have previously colored hair, only bleach can lighten it.

Lemon juice and honey are natural lighteners. You can mix some of each with water in a spray bottle, saturate your hair, and sit in the sunlight.

Peroxide won’t turn your hair green. If anything, it might make it orange. Worry more about chlorine turning your hair green.
