Look at those pictures, what do you think about blond and brunette variant for same person?
I think blond hair make girl more soft and tender
And brunettes are very bright
Make up and PMU is one of ways to make our contrast higher
And we have to be careful!
Pay attention for a most darkest and most white shades, they are the limit of permissible, all others are will be break the natural harmony!
If you we will try to find analogs of her color from hair , eyes, lips, skin we will get her colors passport
If do a contrast there, where it should not be, this place becomes the most appear-ant and brighter on a face.
If you increase the contrast, it makes a woman brighter and more noticeable, but we must do it correctly and to find the right balance. By adding in one place would be unwise, for this you cannot leave everything else unchanged.
For me color of the brows don't depends from hair color but depends from contrast and motivation , for example:
Gwen Stefani is girl with very high contrast white of eyes clean and her iris is very dark
She can have many variants on her brows and all of them looks nice and change her look a little bit
What is better ?
I think it depends of her motivation, if she is very strong beauty motivated and girls who dye hairs in totally different color are beauty motivated more than 100% and may be individual - like Gwen, her style like modern Merlin Monroe many years, so I'm sure that better to do decorative intensive brows, but not too dark, because without make up, she looks like angel, and better too keep it, but ask her, maybe she doesn't need angels look even at home.
And one more example
Dita Von Teese
Sometimes we have to think what is better, keep it like this or tried to change, because color of natural brows hair can be very dark or blond, and you knows that's very difficult to change color for this type of brows.
She can be blond or brunette but strong black brows hair 🤔🤔🤔 better to keep it.
Look at natural and motivation and try to find compromise. Girls who dye hair are beauty motivated 👍🏻👍🏻👍🏻 and loves decorative, just try to understand, romantic or cold style they are.
Ok, remember that for make up there are two ways, make lady brighter or use colors from her color limit, from her colors passport. With more decorative variant your clients will look more aggressive and older some times. Like on this pictures
Here make up artist use colors darker then their natural, and yes their clients became brighter but more aggressive, and older at the same time.
And here is example of make up with natural colors and this ladies become brighter and looks amazing
