Eye colors
There are a multitude of different genes and factors that can affect the color of your veilhorn's eyes.
When designing your veilhorn you have two options:
- Do you want your veilhorn's eyes to be the color of their elemental alignment?
- Or do you want the eyes to be naturally colored, determined by their genes?
- Horses with more than one dilution gene usually have lighter eyes. A double cream dilution always results in blue eyes, no matter what other dilutions the horse has (the only exception being pseudo-albino dominant white).

You can give your character any pupil shape you want.

Brown eyes
Any shade of brown, anywhere from very dark near-black to almost golden brown.

Hazel eyes
Hazel brown, olive-green-ish, a mix of green, brown and gold hues. *Cream pearl can choose between hazel and blue.

Blue eyes
Light blue, can be bright saturated blue, or more grey "steel" blue. *Cream pearl can choose between hazel and blue.

Slate and dark blue eyes
Caused by:
Blue diluteAny shade of blue including dark blue, cobalt, and grey.

Tawny eyes
Caused by:
Tawny diluteTawny eyes have warm tones and can be any shade from bright/rich brown and golden/orange to peachy pink.

Blue tawny (purple) eyes
Caused by:
Blue and tawny combinationWhen both blue and tawny is present, the eyes will be a mix of tawny and slate, causing a grey or mulberry-purple shade.

Pseudo-albino eyes
Caused by:
Pseudo-albino dominant whiteRed/pink/salmon/golden eyes are caused by the pseudo-albino optional effect of Dominant white.

Other colored eyes
You may always optionally color the eyes after your Veilhorn's elemental alignment (restricted to the colors of that element). Shimmer can also optionally affect eye color (restricted to the available colors of shimmer present).

Heterochromia
Heterochromia is free to add and doesn't require specific genes, but the colors available depend on the genes/patterns of your Veilhorn. For example you can have one naturally colored eye, and one eye colored by the elemental alignment, but you may not use colors not present in your Veilhorn's genes/element. Some white patterns can cause heterochromia if the white pattern is only touching one eye.
