Color & SHape
Butterfly should create the shape of a butterfly wing on your ketucari.
Butterfly can be any color that is be bright and saturated.
You may use up to three different colours, with gradients or thin stripes between them to smooth the transition.
It also has normally a soft, white shimmer on it.
If using white, be sure that the marking does not look similar to minimal white.

These are examples of acceptable Butterfly colors, though you are not limited to this palette. These colors are vibrant and saturated, as Butterfly should be.

These colors are too desaturated for butterfly. The only time you have the option of making butterfly this desaturated is if you ketucari has the dilute, smokey, or flaxen genes.
Range
Butterfly may appear on any part of the body. It must not cover more than 50% of the body, but must cover enough that it is immediately recognizable.
Interaction with Other Markings
Examples for the use of Butterfly:
Stripy version
Smooth version

You also may make this gene slightly transparent, so the genes beneath it can shine through.
