My average Brunette client adds some hand-painted highlights to the ticket at least once or twice a year to add movement and dimension to their all over base color. A little can go a long way. But this is a good example of a one tone, deep rich brown done successfully. It is the darkest brown before black and reflects light when it can often fall flat. This can really be a "look" to pull off and here it is done really well. I'd recommend it for the client who is always made up and dressed up, who wants to stand out in a crowd. On average however, this would be too severe for the average client and it could benefit from a little light and movement.
