Bracelet colour ideas for guys?

i’m making my “boyfriend” a bracelet, and he wants me to choose the colours. I need 4 colours that a guy would like! thanks <3
i've tried to as him what colours he'd like, and he doesn't say anything.. he's stubborn -.-

Well, that’s very hard to answer, since guys have different taste in colors, you should ask him what he likes, or at least choose colors that he usually wears.
