In your ketucari's genotype, washout is denoted by the letters "nWt" (heterozygous) or "WtWt" (homozygous).
In its heterozygous form, washout has a pass rate of 60%. Homozygous washout has a 85% pass rate.
Washout must be a lighter 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 lighter. Washout may be pure white.
These colors would be acceptable for this base color. They are either a lighter version of the base, or a lighter 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.
These colors would be unacceptable for washout. They are either darker than the base coat or have too drastic a hue shift.
There is no minimum for washout, but it must always be visible (unless a white marking covers it) and cover at least 10% of the underside. Below is the maximum range for washout.
Our starter Eraku has an example of 'absolute minimum' we look for to ensure Washout (and other genes like it such as Mud and Tar Pit) are present:
Interaction with Other Markings
Here are some small accents you can add to your designs to make them more unique!
This gene must be predominantly hard-edged, but may have small areas that fade out, such as the white near Ashoka's eyes.
You may use up to three shades of the same hue in washout. These colors must be layered inside of each other, like below. Be careful with how you layer the colors and create the edges, as your design will be rejected if it too closely resembles merle.
Washout may have a subtle gradient, like below. Gradients that are too overbearing will be rejected.
Small cut-outs may be present in the marking, like below.
While washout generally calls for "natural" edges, stylization is allowed to some extent. Excessive stylization (such as making your ketucari look like it has tribal tattoos) will cause the design to be rejected. Here are some examples of acceptable washout stylization:
