This item applies cs to a colonist's genome via design update.
When Countershading is applied to a colonist, they may have an additional colour from that base coat with very noticible gradients and shifts in the base coat. This can go slightly outside of the base coat range and may include Cream, Charred, and Silver. It should not come from another colour range other than the base coat, unless affected by artifice.
Countershading may have an extra tone, so long as it is also from the base coat range or, in the cases of monochrome bases, either from the same base coat range as countershading or said monochromatic countershading.
It can be compared with a common marking found elsewhere: Pangare.
Countershading is always heavily gradiented and soft. It never has hard edges.
Monochromatic Colonists
The exception to the rule on colour ranges is in monochromatic colonists: White, non-tinted Silver, or Black, or their other-species counterparts. In these cases, the countershading can take on a more saturated colour from one of the other base coat ranges for that species. This can lead to delightful combinations that look like seal bay horses, etc.
