Hello everyone, so recently I wanted to dye my hair this light brown colour that I saw online. I dyed it and the second photo was the final result. How do I get from my result to the color of the reference photo? I know the reference is probably heavily edited and that the color depends a lot on light and other stuff, but how do I get the closest to that brown? Please help me, I am totally lost.

Forgive my grammar, English is not my first language.
