Depending on the color I need, I use either just a matte powder eyeshadow and brush it on, or first I use a stick concealer to lighten my brows then use the powder eyeshadow on top. I don't usually go all the way to the extreme to match the wig color because sometimes it looks too harsh. I just go for something that will look close and natural. I did that for my make-up test for Juvia
and my brows I felt blended well without looking like I had this mass of blue just sticking above my eyes.
