Who says brown or black hair said already dark lashes at the base. So you can wear black without any problems day and night . It will then play the type of mascara to create different effects : a volumizing mascara for your sophisticated example makeup, and a lengthening of the day.
Black is also an ally of smokey eyes gray / black, regardless of the color of your hair ! You will understand, we will be happy with eye with a black or gray , and even silver base , but you can also wear it with all the other shades of eyeshadow .
