Melting of butter is a physical change, a change of phase; but the brown color, at high temperature, is an indication of thermal decomposition - this ia a chemical change (change of composition).
Melting is a physical change; but above a temperature the thermal decomposition of butter begin - this is a chemical change.
Butter is a food, a mixture of compounds - not a change.
physical changes from liquid to solid

A physical change
Physical, because the stuff that the butter is made out of doesn't change, just the state, or physical form, that it is in. (solid to liquid.)

As you may know, determining whether a change is chemical or physical can sometimes be a real pain! This particular change is a hard one. If your talking about butter slightly melting on a hot day because it was left out on the counter, THAT is a physical change and is reversible by simply putting the butter into the fridge. However, melting butter on the stove and having it completely turn to liquid and turn a little brown, THAT is a chemical change and is hard to reverse... a chemical change has occurred while the butter was over the heat.
This is a physical change.
