poetry question - senses

[hanenglish]

hello, i was just wondering what the term is when a poet mixes up the senses within his or her poem e.g. "red is the strangest pain to bear". It has been on the tip of my tongue but i have forgotten so, i would be very grateful if you could help.
thanks H x

SYNESTHESIA or SYNAESTHESIA (sin-uss-THEE-zhee-uh)
The perception or description of one kind of sense impression in words normally used to describe a different sense, like a "loud aroma" or a "velvety smile." It can be very effective for creating vivid imagery.

I had never heard of this word!
