That’s a great question. I would describe a blue cloudy sky as cool to the touch. It can be visualized in the mind by putting your hand on cool cement in the shade while feeling handfuls of fluffy pillow batting tumble past in the breeze. As the sun appears, the cement becomes warm, and the soft and fluffy handfuls of batting are gone.
When I was in high school, I was a student aid for a class of hearing-impaired students. I was friends with a profoundly deaf girl, and she ‘listened’ to my music by putting her hand on the speaker to feel the vibrations.
