Yes, that's a good solution.

I was more thinking about application style overrides (much like
style="" in html elements). However, on second thoughts, that would
probably not be a good solution in this case. There is a third posible
way though, if we implemented CSS property matching. In this exapmle,
the resulting CSS would look something like:
MxProgressBarBar {
backgorund-color: red;
}
MxProgressBarBar[value > 0.5] {
backgorund-color: green;
}
