Designing: Rainstreaks



Real Life Examples



  • Rainstreaks is a gene that creates bleached streaks on a ketucari, as if water droplets were running down their sides.
  • In your ketucari’s genotype, rainstreaks is denoted by “nRai” (heterozygous) or “RaiRai” (homozygous)
  • In its heterozygous form, rainstreaks has a passrate of 40%. Homozygous rainstreaks has a passrate of 65%


Color and Shape

Rainstreaks should resemble streaks of water dripping down a surface such as a window. It can form individual small drops, or longer wiggly lines that fade in and out. Rainstreaks can have occasional spots with the streaks, but should not consist entirely of spots.

Rainstreaks can blend out at one end, as seen in the image above-- however, it should always blend out at the “tail” of the drop. 

Additionally, rainstreaks can have softer but still defined edges: 

Or harder edges:

Rainstreaks should have a consistent “direction of gravity” around the ket, though the exact path they take can shift to conform to the contours of the body. This does not have to be straight up and down-- rainstreaks can point in any direction as long as the direction is consistent across the ketucari’s design.

Rainstreaks can change direction regardless of its general direction in the following areas:


Rainstreaks should always be a lighter and desaturated version of the coat it is over, and can lighten markings it passes over similarly to bleaching.



Rainstreaks can appear anywhere on the body, so it has no minimum range. However, it should cover at least 10% of the ketucari.

Interactions with Other Markings

  • If present with Intensify or Vivid, Rainstreaks can instead present by hue-shifting the base coat in the areas it affects.



  • Rainstreaks can have a gradient or fade into the base coat.
