Any hairdressers? Want to get back to this hair color again

So I want to get back to this hair color again (see comments for what color I have NOW). My hair is currently a blackish brown, previous to this I had added burgundy hair dye so parts of my hair was dark reddish brown, however I don’t see any remaining red in my hair anymore. Had would I progress to get to this light brown? And yes I have used boxed dye (I’m sorry) lol
