There are four patterns: bi-color, mitted, colorpoint and van.
Bi-color
  • more white
  • all four paws, their underbodies, chest, and an upside-down ā€˜Vā€™ marking on their faces are white
  • may have a splash or two of white on their backs
  • only their tails, ears and the outer part of their masks show the darker markings
Mitted
  • white feet in the front
  • white boots that go all the way up and around the hock in the back
  • a white chin and belly stripe
  • may have a blaze, star or hourglass shaped atch of white on their forhead and nose
 

Colorpoint

  • classic pointed markings with no white anywhere in their coat
  Van
  • only the top of the mask, ears, and tail, and perhaps a few spots on the body, show darker markings.

Patterns come in six colors: seal, blue, chocolate, lilac, red, and cream.
Points may be solid, lynx, tortie, or torbie (lynx and tortie).
So, there are large number of combinations possible.
