How to remove or correct blue eyebrow tattoos?

I got an eyebrow tattoo that I shouldn't have gotten.
Old eyebrow tattoos, they've faded (turned blue) over time and look tacky.
I would like to remove it through a procedure or correct it to its original color.
I am curious about the specific procedure to resolve these blue discolored eyebrow tattoos.
Is it possible to effectively remove a blue tattoo like this?

I know it depends on the depth of the tattoo and the density of the pigment, but I'm wondering roughly how many treatments and the overall duration would be needed to remove the blue discoloration.

I would like to know if there is a risk of the corrective pigment fading again over time after the procedure.
I would also like to know if it is possible to remove only the pigment without damaging the existing eyebrow hair during the procedure.
