Bruise has turned an odd color. Should I wait a couple more days?

Not unusual. A bruise typically gives you the typical purple and red appearance. As the blood gets broken down by the body you may get the greenish/ yellow tinges as the hematoma resolves.
Bruise. Bruises can certainly change color and look really odd. Depending on the location they can take weeks to clear. However, if the problem is getting worse and painful then you should have it examined.
