> I'm wondering if a better strategy would be to try avoiding recolor candidates that could conflict with the saved recoloring state for fixed registers

If we go down that road, I'm pretty sure we will find cases where the recoloring was working previously and that would fail after such change.
The idea is while doing the recoloring we should have access to every color that is currently available.
