- Bronze turns patterns bronze or rich brown.
- Flaxen turns patterns creamy white or lighter than the base coat. (only affects chestnut-based (ee) coats)
- Silver turns patterns white or lighter than the base coat. (only affects black-based (EE or Ee) coats)
- Chromatic turns patterns into a different hue or saturation.
- Grey can leave the patterns unaffected (doesn't grey out), or leave the entire body unaffected and only the patterns grey out.
Can be affected by Shimmer in many different ways, see shimmer guide for details.
Always goes below White patterns.
Doesn't affect skin, eye or hoof/horn color.
Can optionally affect mane/tail.

Acanthus

Mosaic appears as a patchwerk 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 or 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.

Papilio

PplPpl / nPpl

Appearance

Papilio appears as lacy spots and stripes similar to the pattern on butterfly wings.

The markings are black or darker than the coat, with light and/or white details and accents.

Papilio can display "false eye" spots as seen on peacock butterflies.

Markings are limited to darker and lighter shades than the base coat (including black and white) unless modifiers and/or shimmer is present as well, see modifier interactions and shimmer guide for details on each.

While the examples all show papilio markings starting from the topline of the horse, there is no limit to where papilio can appear (i.e. only on legs is completely fine).

Quill

QllQll / nQll

Appearance

Quill causes wavy striping or barring across the body, mimicing the appearance of feathers - similar to Sebright chickens that have a striking laced feather pattern.

The quill pattern can have alternating light accents and dark markings, and can flow in the direction of the coat hair (but doesn't have to.)

Shroud

ShrShr / nShr

Appearance

Shroud causes a wild camouflage-like countershaded pattern similar to sooty but with more distinct shapes, generally starting from the spine/topline of the horse and reaching downwards.

The shroud markings can be multiple different shades that are black or darker than the coat.

It can optionally have lighter accents around the markings or covering the underside/belly of the horse.

The edges of the shroud markings can be both soft/blurry and sharp/clear, and even have a jagged look mimicing the appearance of long fur.

Both shroud markings and the light shroud accents can optionally affect mane and tail.
