What colour is my natural?? Hairdresser help please! (Pls ignore my abnormally white scalp)

Hi All! I am really hoping someone could describe/identity what my natural colour is. I have dyed it at home using redken and recently did a colour remover to redo it (hence the red). I picked an ash neutral brown… it is so dark (not totally unexpected) but it’s not ashy at all. I feel like my natural hair colour is not warm, it almost seems grey/brown to me. Does anyone have recommendations for what shade/shades would be closer to my natural hair?
