That would be phaneritic texture. Rocks such as granite cooled slowly and are classified as phaneritic rocks (in addition to all the other classifications it falls into. The opposite type of igneous texture is aphanitic, which applies to faster-cooling rocks, such as basalt.

Rough, due to the size of the crystals.
