What should I do with my hair

Okay so my virgin hair is super dark brown but recently I have dyed it intense black blue thinking it will look blue however it came out as black and it shows blue shine under certain lighting, I don’t hate it I actually find it pretty however it wasn’t the color I was aiming for so now I’m thinking of buying direct hair dye the blue color however I’m not really sure if it would work cause I already died my hair (it’s been a month) and I don’t want to dye it a lot because I don’t really want to damage my hair and stuff so when I would dye it I will have to make sure first that it’ll work Help please
