How to naturally lighten pitch black hair?

Ive tried the cinnamon paste and honey for 13 hours. It did nothing. Not even a subtle lightening. Ive been in the pool and in the sun for hours everyday in the sun my hair is so dark, it just looks blue. I tried peroxide. All it did was make my hair brittle and dry. I dont want to bleach it, but I want it really lght. I dont even care what color as long as its more than two shades lighter
