Calling all hairdressers!

I'm really afraid to bleach my hair to lighten the color. That's my last option. So I was just wondering if anyone knew of any at home hair lightening remedies that I could try? I've heard of chamomile tea, honey, and lemon juice and I would love other opinions! I have black on the bottom and red on top right now but the red has faded to a blonde which I'm not worried about but I want to put silver and purple in my hair and have it as a kind of brighter purple where the Black is😩
