Ibimus, be careful with dyeing your eyebrows the same colour as your hair.
Before you try this, make sure you'll really like the look and use some black eyeshadow and fill them in, and see if the look isn't too intense for you. It'll take a bit to get used to it, but if you feel comfortable, go for it.
I used to do my eyebrows very dark, same color as my hair, and it was such a contrast against the pale skin, that was causing me to look "stressed" or overly dramatic.
If you have black hair, the best colour to use on your eyebrows to fill them in is MAC's eyeshadow Smut. its a mix between brown/black and a weird bronzy irridescence that works amazing for a natural look for brunettes/black hair.
If not, Cork is the second best, which is what im wearing in that picture.
