I've got multiple colors for marked, cursed, quarried, bloodied, dazed, ongoing damaged, etc. Sure, my minis tend to "grow" as more and more effects get layered under their bases, but it works for my group, and foam tends to "catch" on itself, so the pieces don't topple over.
This is how I would do it. Or, use the foam tokens by numbering them with a sharpie. It is easy to track effects on red goblin 5 for instance.
