The way I see it is fairly straightforward. If we're going with the theory that each of the souls' colors correspond to a boss fight, we get:

Undyne: Green

Papyrus/Sans: Blue

Muffet: Purple

Mettaton: Yellow

Which leaves Aqua and Orange. Toriel, our first boss monster, doesn't use Aqua or Orange attacks in battle, but Papyrus is the first to use Aqua attacks that we see, so maybe Blue corresponds to Sans and Aqua to Papyrus, leaving Orange to Toriel or possibly even Asgore. It's a shaky logic, I admit, but so far nothing's been confirmed or Jossed so it's worth exploring.
