While both the Horse and Hind are are feminine symbols, they are androgynous in that they are are associated with both the water and fire element. The feminine aspect is represented in the image by the flowing water whereas the androgyny is represented by the paralleled sun and moon. Both are engulfed in red water (blood) the combination of fire in water with the feminine emphasis.

The Horse is externally fire hence the gold (sulphur) coat, and internal water hence the watery eye and it's extremities reflect the tint of deep water. Water (nurturance) within Fire (emotions) nurtures the earthen (action) aspect, represented by the branches growing around the Horse.
The Hind is internally fire, thus it's eye, and the hooves and antlers that emerge from "within" are flame-like. Because it is external water, it's coat bears the colour of shallow waters. The Fire (intelligence) within the Water (nurturance) creates Air (wisdom) represented by the turrets of wind surrounding the Hind.

<the Hind is a doe with gold tipped antlers and brazen hooves.>

TL;DR : Hoofers. I wish I could have emphasized the wind swirls or differentiated it more from the BG, but I couldn't use any other colour.
