The color of natural henna varies and can be a deep burgundy brown, coffee brown, rich maroonish, or any shade of orange or brown, such as the picture to.
The color of your actual henna tattoo will depend on a number of factors including, how fresh the henna is and what it is mixed with, how the skin was prepared before applying the henna, how long the moist henna was in contact with the skin, what part of the body was hennaed, and how the dried henna was removed.
it's important that you only use natural henna and you know what other ingredients are mixed with the henna.
