Infravision

Creatures with Infravision are able to see into the infrared spectrum. Creatures and objects that produce heat stand out in particular from their environment. Infravision is blurry and makes it hard to determine the exact distance and shape of objects it sees. The intensity of a heat signature determines the color of the object, with blues and violets the coolest signatures and oranges and reds the hottest. Ambient temperature can significantly affect Infravision, with hot environments able to make a creatures heat signature. Creatures with Infravision can also see normally.

Infravision is a Visual sense.
