When a peacock molts, do his feathers come back with the exact same coloration patterns, or do the colors change from year to year?

Usually when adult birds molt, the new feathers have the same color as the old ones. There are exceptions, male American goldfinches change colors each time they molt, from bright summer color to drab winter color and back again. Young birds usually change color and pattern to some degree when they molt to adult plumage. Birds like eagles and some gulls may go through 4 years of changes before they have full adult colors.
