Recently I have grown very fond of coloring my eyebrows different colors! Purple, pink, blue! Love it <3 I know a lot of people with super dark bushy eyebrows who have issues coloring them, But i'll tell you right now girls that I have the darkest bushy eyebrows ever! (although most of them are shaved off, except for the base of them) but all I use is a regular white eye pencil to coat them in and whatever color eyeshadow I want with a small angled brush, then smooth the edges with a Q-tip. Works like a dream.
But if you are more into natural brows, I've been using the Too Faced brow envy kit for a long time now and it is wonderful! I highly recommend it.
