Oops... I shouldn't have had breakfast before hitting "submit". ;-)
My first choice would also be to biff the black and get new stuff.
But if it's not an option, you can make it work. It depends on what your making it for too. If it's a quilt for the dogs (don't laugh, I've made several! lol) it's a little different to a family heirloom that will be passed down for generations. Likewise, if it's your first and you just want to get something done, then it's the process and not the end product. It's your call really. :-)
