I’m not sure what they mean by “feels.”
All I can assume is the person associates the combination with something. For instance I associate certain smells with certain colors. That’s not a perfect analogy, but I think something that affects one of our senses (sight in this case) can translate to another (touch).
Pink and white is soft and pillowy to me.
I’m just not sure if the person means an emotional feeling or an emotion along feeling.
