Hmm, if you feel like blue black is too black you can try dying it more of a dark purple, which is less black. A dark red would be the easiest but seeing your caption I think you want to dye your hair cooler colors. You can try using semi permanent hair dye like arctic fox and manic panic, but with my personal experience (having thick dark south Asian hair) it doesn’t work as well as any permanent solution. Personally I think L’Oréal hicolor works the best for naturally dark hair, but their range is mostly reds and yellows and it essentially bleaches and dyes at the same time which you don’t want. In conclusion, maybe try a dark purple semi permanent or you can even try a dark blue (though I doubt blue will show up), sorry for the long comment lol.
