The hard, bone-like part of her hoof was a whitish-grey, while at the heel there was a dark-colored heart—almost the same color of flesh he’d seen under the nurse’s tail. His cheeks burned at the memory, and he covered his embarrassment by leaning closer, seeing small chips in the purple above Twilight’s shoe. Underneath was the same white-grey color as on the bottom of her hoof, and he realized it was some kind of paint or hoof-polish, which explained how their hooves were nearly indistinguishable from the rest of their coats—they clearly painted them to match.
