Cones are responsible for colour vision; the way in which the opsins in cones react to light are what allows the perception of different colours. An infestation of roaches, rodents, and other insects can certainly attract snakes. The ability to sense infrared thermal radiation evolved independently in two different groups of snakes, Boidae and Crotalinae. These pits, not eyes, actually are thought to render images of prey in the snakes' brains. In fact, snakes cannot blink. Some pythons and boas can also sense heat in this way.
