I hate to just link to Bernie's page on this, but
https://berniesanders.com/issues/racial-justice/ discusses his various policies (violence, economic injustice, environmental problems, etc.) in relation to minorities fairly well. Now, you're absolutely right - a lot of those policies are colorblind. That said, it's true that
even so many of them would greatly benefit people of color, like raising the minimum wage to $15, banning employers from discriminating against employees by criminal history and re-instating voting rights for people who had them stripped away by felony convictions, ending the war on drugs, etc. He does have some things he lists there that are specifically intended for the purposes of rectifying racial disparities like "address[ing]address the inadequate environmental cleanup efforts of Superfund hazardous waste sites in communities of color."
Some things though can't really be legislated away. It's already illegal to discriminate against someone for their racial/ethnic/etc. background when hiring - it's not like you can make it any more of a law to "not pass over that buy because his name sounds black." A lot of that sort of thing would have to come from society changing itself. (edit: although I just read the post on the last page with the suggestion about bias testing and that seems like a good idea)
I don't think either candidate is really quite adequate for meeting the needs of minorities; Bernie obviously had a blind spot that he's been working on and Hillary hasn't really promised any sweeping changes herself. They both seem pretty similar in their stances but Hillary has better messaging.
Now, as someone who mostly supports Bernie for the sake of pushing the overton window, I do think
actual socialism would be greatly beneficial to non-whites since it would massively elevate their political/economic power. Not to say that real socialism (as in, the workers controlling the means of production) can't be rife with racial problems itself. Unions obviously have all sorts of messy history with race. But to me that would be the best way to ensure that people at the bottom of the socio/political/economic ladder get a real say in the matter. Unfortunately that's a long way off or may just never happen.
