Koi

Koi is an irregular marking present anywhere on the Xunari, either symmetrical or asymmetrical, and can have a hard, soft, or textured edge. It cannot be a single large patch of colour, and very small patches must be limited lest they mimic barring or ember. These patches are solid, meaning they have no holes within them unless modified by ticking, and they can be either darker or lighter than the base coat.

Koi spots should be generally larger than the eye, but may be interspersed with some smaller than the eye so long as there are a majority larger, so as to not be confused with other spotting genes such as Marozi or Truespot. The largest Koi patches can take up about 1/3 of the body, but should not look too much like Saddle, Nullified, etc in its placement and shape.

In its heterozygous form (Koi koi), it can only be one colour or tone but when in homozygous dominant form (Koi Koi), this can increase to up to three different colours, which can differ in light or dark. Unlike Marozi, this difference in coloration is per-patch, not within a patch. One spot cannot be multiple colours, though there may be moderate overlap between spots.

When affected by artifice, either one of the colours (in heterozygous or dominant) or all (in dominant) may be the affected colour.

Paisley is a lineage-linked variant of the Koi marking. It allows for the shape of koi to go from organic patches and large spots to include some spots that appear curved, similar to a solid half of the ying-yang symbol. It is inspired by the paisley design style. Be aware when designing that it shouldn't look too similar to eyelet and the above rules for colour/tone still apply.

Only colonists who have the following natives in their visual ancestry or have a visible ancestor with paisley koi may, in turn, have paisley koi.

Paisley koi does not show in the phenotype.
