Appearance
Astral covers the horse in stars, anywhere on the body. It can be any color and can optionally have subtle color shifts. Can go above or below white patterns. Starry areas on the coat/mane/tail can also have any colour, appearing as a galaxy or soft gradient. Eyes, horns and hooves can not have their colour altered by astral, but can still be starry/sparkly.
Astral can optionally affect other genes, allowing them to be sparkly/starry in any colour, and optionally be slightly translucent/ethereal.
Astral only causes stars and small spots, it doesn't create moons or planets or other celestial bodies. The stars can be as small as tiny sparkles, or as large as twice the size of the hoof. The stars themselves can also be sparkly.
Astral can cause a starry "halo" effect, floating above or around them.
