With the extreme heat and pressure causing the metamorphism into gneiss, the constituent minerals recrystallize into bands, usually alternating from light colored to dark, perpendicular to the direction of the pressure which is being applied. The exact cause of the banding is not fully understood at this time.
The metamorphism of granite would likely result in the formation of gneiss, a coarse-grained foliated rock with distinct bands of minerals. The high temperature and pressure during metamorphism would cause the minerals in the granite to recrystallize and align, giving gneiss its characteristic banded appearance.
When granite is subjected to heat and pressure, it undergoes a process called metamorphism and can transform into a metamorphic rock called gneiss. The mineral composition and texture of the granite change during this process, resulting in a foliated texture and alignment of minerals in the gneiss.
When gneiss is formed, quartz, feldspar, mica, and other minerals of granite are rearranged into alternating light and dark bands or sheets. This distinctive layering is a result of the intense heat and pressure that gneiss is subjected to during the process of metamorphism.
An agent of metamorphism related to temperature is heat. Heat causes minerals in rocks to recrystallize or change mineral composition, leading to metamorphic changes in the rock. Temperature influences the degree of metamorphism and the types of minerals that form during the process.
During metamorphism, the texture and mineralogy of a rock can change. Texture refers to the size, shape, and arrangement of grains within the rock, while mineralogy refers to the types of minerals present in the rock.

The color of sedimentary rock changes during metamorphism due to minerals. New minerals introduced can change the color of the rock.

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.
A type of metamorphic rock similar to granite is gneiss. Gneiss is a foliated metamorphic rock that has a similar composition to granite but displays a banded texture due to the alignment of mineral grains during metamorphism.
During metamorphism, the texture and mineralogy of a rock can change. Texture refers to the size, shape, and arrangement of grains within the rock, while mineralogy refers to the types of minerals present in the rock.
During metamorphism, crystals can grow larger through a process called recrystallization, where existing minerals rearrange their atoms to form larger crystals. This can happen due to changes in temperature, pressure, or the presence of fluids in the rock. So, yes, crystals can grow larger during metamorphism.
