It's colorless. The green you see when an AC line gets compromised is the oil which lubricates the compressor, not the refrigerant (by the way, it's only actually Freon if it's manufactured by Dupont and marketed under that name).
CFCs and HCFCs are colourless (Freon is a brand name)
It is a colorless gas.
Its odorless and colorless.........
Freon isn't a single compound, it's a family of related chemicals. Most freons are colorless and odorless.
R-12 freon is colorless and odorless...............
Freon is colorless on its own. The refrigerant oil can have a tan color, while a leak detection dye would be yellow.
Freon is added to the low side of the a/c system, that is the big line and the capis normally blue in color.
There is R-11 Freon Gas as coolant and R-11 for cleaning and there is recycled R-11, what is the color of containers (bottles) for each
r134a is a refrigerant (freon) added to the air-conditioning system. It has no color, but can be purchased with a dye (usually red) in it to detect leaks in the system.

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. More Information on Freon Below: (It CAN have an Odor, and is Dangerous in enclosed spaces!) http://www.ehow.com/list_7631527_symptoms-freon-leak.html http://www.dhs.wisconsin.gov/eh/chemfs/fs/Freons.htm http://www.epa.gov/chemfact/f_freon.txt
Is r-22 Freon compatible with r-134a freon?
Freon R134 is a gas used to charge A/C units. It does not have a smell or color. ...Actually the proper name is not FREON® which is a DuPont trademark brand of HCFC based refrigerants, like FREON® 22. The actual R-134a DuPont Brand name is Suva® 134a... and R-134a DOES have an odour, it is a difficult to detect, "sweet , ether-like" odour.
Contains no Freon. Freon was banned beginning in 1996.
