No, they get mixed up together. The chemical compostition of the minerals don't change.
The colour of granite does in fact change. For example it will change during the weathering process where feldspar minerals will change to clay minerals such as kaolinite. If the degree of weathering is high this can significantly alter the colour of the granite.
Due to density.
Physical or mechanical weathering
Air, water, and impurities can change the color of a mineral.
