I have light hair and lashes, and I currently use a dark brown or brownish black mascara, because it is the lightest I can find. I don't like clear mascara at all, my lashes are very light blonde and need some color but it'd be nice to find a light brown color. Does anyone know of any brands that may make one? thanks
(just for the record I'm not the one who gave thumbs down. Thanks ladies for the answers)

I really like Almay's One Coat Lengthening in brown. It's a nice light brown. Maybelline Define-A-Lash also has a good brown.
Pay attention to ones that describe the brown as "soft". There are a lot of brands that label their light browns as "soft brown".

Rimmel London or Clinique are both very reliable sources. Rimmel is cheaper, but Clinique is better, but probably 10 o 15 bucks more.
