Designing: Koi




Bullet; White Koi creates hard-edged dark patches. 
Bullet; White In your ketucari's genotype, koi is denoted by the letters "nKo" (heterozygous) or "KoKo" (homozygous).
Bullet; White In its heterozygous form, koi has a pass rate of 35%. Homozygous koi has a 60% pass rate.


Color and Shape

 This marking should resemble the dark patterning on Utsuri koi:……

Patches should have irregular edges. Be sure that it doesn't too closely resemble spotting.

Koi must be a darker color of your chosen base, with a minor deviation in hue. It can also be a fully desaturated color of the base, as long as it is darker. Koi may be pure black.

Dskyes by Matriarchs-Haunt 
These colors would be acceptable for this base color. They are either a darker version of the base, or a darker and desaturated version of the base. The last color on the right shows a minor deviation in hue, and is slightly more yellow than the base itself. Notice that this small change is not overbearing.

Dskno by Matriarchs-Haunt
These colors would be unacceptable for koi. They are either lighter than the base coat or have too drastic a hue shift.


Koi can appear on any part of the body, but must be immediately recognizable. It may not cover more than 50% of the body.

Koi spots can be any size, but should not be used to mimic another marking, such as Dusky Points.

Interaction with Other Markings

Bullet; White All markings can be layered under or over koi.
Bullet; White Koi can be influenced by infernovapor, and segment.


Here are some small accents you can add to your designs to make them more unique!
