Thank you jaclaz, for Italian translation correction! Idea with colors is that hotter color means higher number of pixels per meter or pixels per foot.

It is only about conventions, in thermal images, usually red is "hot" and green/blue is "cool", but then it depends on what you use it for, if you do house thermal imaging, to check if insulation is good, if you do it from the inside cool is "bad", but from the outside hot becomes bad (in most common cases when outside is colder, i.e. winter, but it reverses meaning if you are testing for an air conditioning system in summer).
