ChCh/nCh
This marking creates irregular small stripes/spots, forming a shape remembering a chessboard.
In its dominant form it can extend further on wings, head and belly.
This marking is really similar to lizards' back
Can be darker but of any darker color!
Chess is basically a more texturize and blotchy version of Oil, you start witha big patch and proceed erasing holes in it, addint spots and blobs, connecting the erased holes and so on. Some areas can be more thick than others (meaning can display no holes )
In dominant the marking can have some rows of cells filled with a lighter color (any color is possible as long as its lighter than the marking itself!)
