The only problem with the basic balls are that the color isn't good for the horse body and I can't change the hue without changing the horse bodys hue too
Try changing his skin tone to Dark. The resulting brown skin color provides a rough match for the chestnut coat.
Also - you may want to tweak the position file in Animtools. Since the male character is completely immobile, the balls will never actually
move. If you extend her tween range slightly, then she'll be able to approach near enough to lick the balls (and thus send them swinging back and forth).

Make the horse stuff his pants. Costume layers ignore HSL sliders.
The penis obeys HSL sliders, though. If we're forced to make major HSL changes in order to match the balls to the coat, then the penis might end up looking out-of-place.
Because when I asked if anybody would ever bother with his balls, no one replied, which I took to mean as a "no" and thus any effort I put into figuring them out would be wasted.
I think that your assessment was correct -- the balls involve six partially overlapping layers with different origin points. It's
possible to draw a replacement set, but it would be tricky for a novice modder.
The greatest virtue of your FLA template is that it prepackages the ActionScript and layer-assignment and per-frame update stuff, so that a novice can create complex mods by simply
drawing the desired shapes onto the canvas. When the actual drawing work is complicated (due to implied perspective, overlap, composition, and rotation effects), we can't offer the newbie much of a head-start.
