Although codes differ, they all represent the same level and reflect.

Level and reflect equivalences are a useful reference, but not identical. Each brand has its own chemical formulation, pigments and technology. Two "equivalent" codes will produce similar but not identical results. Factors like natural base, porosity and color history affect the final outcome.

Generally yes. If you maintain the same level and reflect, the result will be very similar. However, a strand test is recommended when switching brands for the first time, as formulation differences can produce slightly different nuances.
