Importance depends on the situation. In a simple bar gig, I'm sure it doesn't matter at all, be yourself, use whatever you want.
If you're auditioning for a gig with a pro act as a sideman, Reba will want you to blend in and disappear, so don't use a bass painted with a big bullseye on it. I've also heard MANY stories about session auditioners - mostly in Nashville - getting turned down discriminatorily for showing up with six and seven string basses.
The band I gig with now dresses in black and has all black guitars. I'm sure I could show up with a red bass and nobody would get in a tizzy fit, but it looks more professional given the fact that everybody plays and dresses in black. In the end it really doesn't matter with a cover gig like this, but its such a simple choice for a small improvement that I go with the grain.
