The rule of thumb for brow color is

• dark haired people should go one or two shades lighter than the color of hair on their head
•  light haired people to go two shades darker than the color of hair on their head

Rules are only "conventional wisdom" and this may not be best for you.

We find most of our customers prefer eyebrow powder and tell us they find it very soft and natural in appearance.

Many African-American and Hispanic women report that the dark brown powder works exceptionally well (although we do get some who report black was best). Asian women tell us that the soft black powder creates a beautiful look for them.

Brow powder matched brow hair color here. You can't tell where the powder ends and the real brow hairs begin. The brow powder is as close as possible to the color of the eyebrow hair. To see the whole how to section  click here.
Notice in this image the brow powder covers both the skin and hair to create a completely new brow  color.  Sparse and light brows can go with a color different from their  brow hair.  To see the whole "how to" section, click here.
