Appearance
Mosaic appears as a patchwork of darker and lighter variations of the basecoat. Darker patches can be anywhere between completely black to only slightly darker than the basecoat. Lighter accent patches are optional, and should be fewer and smaller than the darker patches, and only be slightly lighter than the basecoat (a dark-colored horse cannot have near-white light accents).
Mosaic markings should appear natural similar to how chimerism appears in real life horses, and should not depict specific objects or symbols.
The mosaic pattern has the unique ability to also affect other patterns and white patterns, letting the markings and patterns display differently in each mosaic patch. For example (as shown in the appaloosa example) the bay base coat has snowflake appaloosa (an optional appearance of leopard appaloosa), while the dark mosaic patches shows regular leopard appaloosa.
Mosaic should never "turn off" other present markings or patterns, for example (as shown on the blue chestnut example) all the mosaic patches still shows pard - just with different spot shapes.
Always goes below white patterns.
