Koi

nK/KK
💧 Aquatic Rarity: Uncommon

Koi, like the fish it's named after, creates patches of white and dark colors on up to 50% of the kukuri's coat. The white layer takes on a Piebald-like look while the dark layer can range in appearance.

The white of Koi layers over everything except Crested. The dark layer can layer freely above or below the white layer or any other marking.

The dominant form (KK) can cover up to 90% of the kukuri's coat!

A Guide to Koi

Koi edges

Koi can have hard, soft, or textured edges, it may also have fur texturing. However these edge types should not be mixed, nor should they be too extreme!

White and Dark split

Koi does not need to be a perfect split of both the white and dark colors! It can be majority dark if you want. As long as a bit of both are showing, you can split the amount however you wish! But note that you can not go over the allowed coverage. More white means you have less room for more dark.

Koi AND HETEROCHROMIA

Koi can create heterochromic eyes almost the same way as the mutation does, but it is not inheritable to any offspring. This doesn't act like real life piebald or pinto, it does not change the eyes blue. It takes the colors from the parents only, unless the parents are albinos (in which case you can use grandparent's colors).

Heterochromia can only appear when the white area covers one of the eyes, and not the other. Partial heterochromia is not allowed for Koi. Also unlike heterochromia mutation, Koi can not make the eyes have different colored scleras.

If a kukuri has both Koi and heterochromia, one eye may be affected by Koi (one color) and the other may be affected by heterochromia (two colors), for 3 total eye colors. There may not be three colors in one or both eyes!
