How does Piers Anthony use imagery in Blue Adept?

Examples of Imagery:

"'No horse could maintain such a pace, so smoothly- yet the Hinny ranged beside the blue stallion, now and then covertly turning a sleek ear on him: she desired the service only he could serve."

"'And I realized that in the guise of a request, the lad was proffering a gift of what was most dear to my father's dreams. It was Blue's way... And something heaved in my breast, not love but a kind of gratitude, and I knew that though he looked to be a lad and was in fact a nefarious magician, he was also a worthy man.'"
