Out of the MANY different types of air conditioning and freon, I can safely say many of them use oils that are brightly colored. Green, fluorescent green to be clear. And I do mean a green that will startle you in any quantity. The oil usually has a near mineral oil smell. It is very thin as oils go, and will spread out over a large area typically becoming so thin that color is hard to determine if an oily spot is found. These oily spots indicate a leak.
Note: some appear yellowish but all that I have seen are very very noticeable.

What does freon smell like?
Odorless. What you are smelling is antifreeze, leaking from the heater core in your car. I DISAGREE: Freon smells a bit like ether and should not be inhaled. Freon is a gas that does not have a color or smell, however, you should NOT breathe it.
