How do i know the optimal color for my eyebrows to pick the right dye?

[Weter]

I have medium brown(4-0) color hair and white skin. Im planning to soon dye my hair darker, but i also saw some people dye their eyebrows to 1-0 really black just to find out that they look stupid with them but the black color cant be undone and they have to trim eyebrows entirely
