i found this in another forum
"Karisu is SO not a blond, too. ^^ I have very dark hair, and black eyebrows. What I use:
For more "natural" colors (auburn, blond): "Cover Grey" sticks from my local drugstore - look like lipstick, meant to cover grey streaks in hair, come in 4 diff colors: black, dark brown, light brown (looks like auburn), blond.
For other colors: Ben Nye creams - I use white as a base and then grey over it for Dilandau (with sometimes a touch of purple eye pencil in there too. )
Blond "Cover Grey" gives my eyebrows a rather light brown impression, which works great with blond wigs. Remember that for an optimal look, eyebrows should be a bit darker than the hair, otherwise you look washed out. (And eyelashes should be same, or even darker - all the way to black. ) *happy she doesn't need mascara on black eyelashes ^^*"
