how do i lighten my eyebrows

first two photos are of my eyebrows with absolutely zero product in. i want to achieve a look like the last 3 photos. how can i do this? i am guessing i bleach and then dye them but what colour? i still want them to be black but just less dense (i would say the other girls still have black eyebrows just less dense than mine). do i get a grey or brown dye? but i want black eyebrows not grey or brown 😭💔 is this even possible. help please!!
