Darkvision

Those with darkvision have sight in complete darkness, although this ability is usually limited to a certain range and their surroundings generally appear only in black and white. Darkvision does not allow the viewer to see invisible things, and does not afford an enhanced ability to see through illusions. Creatures may possess darkvision as an inherent trait of their species (e.g. androids and ysoki), due to technology, or because of magic.
