Nope :) There are types for Electrical fires, Paper fires etc, which use water or foam or powder. We had three different types in our workshop. All different colours. Wont give game away :)
Red had water,, Green had foam, and Blue I think and Black was Carbon Dioxide As far as I remember. Never had to use one in all my working life but they had to be serviced every year and documented.
Exactly what I posted. I will tell you, that every member of the class (all well trained in fire fighting) got it wrong. And we had to retrain every 3 years, but this one threw a wobbly at us.
Class A Extinguishers
Fire extinguishers in the Class A category have a green symbol on the front of the canister with a picture of a burning garbage can. These extinguishers are used on ordinary combustibles, such as wood or paper, and typically contain plain water.
Class B Extinguishers
Class B fire extinguishers have a red square as their symbol containing a picture of a gasoline can with a burning puddle inside. These are used for flammable liquids such as gasoline or oil. They typically have carbon dioxide or foam inside.
Class C Extinguishers
Class C is used for energized electrical equipment that has caught fire, such as a fuse box or an outlet. These have a blue circle with a picture of an electric plug and a burning outlet as their symbol. They typically contain a dry chemical to put out these fires.
Class D Extinguishers
Class D extinguishers are usually only found in laboratories. They are for use on chemicals that have caught fire, such as magnesium or titanium. The symbol for this class is a yellow star that contains no added picture.

Prior to 1st Jan 1997, the code of practice for fire extinguishers in the UK was BS 5423, which advised the colour coding of fire extinguishers as follows:
Water - Red
Foam - Cream
Dry Powder - Blue
Carbon Dioxide (CO2) - Black
Halon - Green (now 'illegal' except for a few exceptions such as the Police, Armed Services and Aircraft).
New extinguishers should conform to BS EN 3, which requires that the entire body of the extinguisher be coloured red. A zone of colour of up to 5% of the external area can be used to identify the contents using the old colour coding shown above.
