This item applies Rn to a colonist's genome via design update.
Roan is a gene found across various species on Xiunus. The gene features an intermixing of white and coloured hairs in the coat that, when thick enough, lightens the appearance of the coat along the back and neck of a colonist. While less often on the limbs, it can be frequently present on the face and head. Oftentimes there will be circles or rounded holes called corn-spots within the roaning that show the solid coat beneath. Due to the gradual nature of the lightening, some colonists have a rather smooth (gradiated) transition between roan and normal coat, while others can have a more mottled transition.
Roan is a top-level marking that affects the mane and all other markings, besides white spotting genes. On occasion, it can appear to fade into the appaloosa markings, but due to the location it rarely condenses around sabino.
One might think of Roan as the reversal of Dapple.
Reticulated roan is an inherited variation of roan that looks remarkably like reticulated giraffes, with the addition of the gradient fade-out that Roan has. Instead of circlular or rounded corn-spots, the holes in the roan are large and can appear almost geometric—though they must still hold a deal of organic shape and structure. Placing a grid or other inorganic pattern without smoothing between holes is not an acceptable display.
The outer edge of reticulated roan must fade out with a smooth transition between roan and normal coat.
Only colonists who have the following natives in their visual ancestry or have a visible ancestor with reticulated roan may, in turn, have reticulated.
Reticulated roan does not show in the phenotype, but roan as a marking must be present.
