Need some color help

I'm signed up for a quilt class later this month where we'll be making a Hunter's Star wall hanging. This can be done in 2, 3, or 4 colors but I've decided to keep it simple and use just 2. And they need to be high contrast.  Here is an example of what it could look like.

So I'm looking for some input into what colors to use.

• black and white???
• gold and brown (or black or cream)???
• green and something???

I have made way too many blue and white quilts in the past couple of years although it is one of my favorite color combos.  There is a perfect spot for a wall hanging in my guest bedroom, which is all done in blue and white.  

Should I stick to my old favorites?   But maybe I need to step out of my comfort zone a little more. So . . . I'm looking for ideas. HELP!!!
