Inverse Rabicano

Inverse white creates the opposite pattern to its counterpart white pattern. In the case of inverse rabicano, the base colour shows through the white in brindle-like lines around the flanks and belly, sometimes leaving the top of the tail as the base colour like an inverse skunk tail.

When inverse whites are combined with their regular counterpart on the same locus, it creates an "outline" of the pattern, a thin line of the base coat where the edge of the pattern or spots would be leaving the rest of the coat white. 

Inverse white does not affect residual white or any Birth Anomaly whites.
