COLD: The American Sign Language (ASL) sign for "cold"

The sign for "cold" means "cold temperature."  It doesn't mean "to have a head-cold" or to be sick. Use your arms to represent shivering.
 

COLD: 

Sample sentence: "Do you like cold pizza?"

To sign "very cold" use more facial expression, hunch your shoulders more, and move the "shivering of your arms" faster and tighter.

very-COLD:

 

WINTER:
Many people use the sign "COLD" to mean winter. This works well in context but if there isn't much context I prefer to initialize the sign "winter" by using a "W" as the handshape.

REFRIGERATOR:
You could sign refrigerator by initializing this sign, but  I recommend you just spell "REF."

Here is a sign for refrigerator that initializes the sign COLD with "R" handshapes to mean refrigerator:



Remember, I recommend you just spell, R-E-F. Some people feel that the initialized form of the sign "refrigerator" is signed English.  I disagree, but do the sign the way your local instructor wants it just to be safe eh?

GRAB REFRIGERATOR DOOR (depictive sign):

You could also initialize the sign for "DOOR" to mean refrigerator.
