Below are some of the colors French Bulldogs come in.

 Black Mask

The black masks have  solid black across the muzzle and sometimes across the eyes as well hence the term "black mask". Above is a Red Fawn Black Mask.  Below is a Black Mask Fawn with black across the eyes. Another variation using the Black Mask is Black Mask Brindle (not shown).

Black Mask Fawn

 Brindle with White

Brindle with White color refers to a dog that is black with a pattern of red, brown or fawn hairs found in the black.  Breed standard requires only a trace of brindle therefore just a few hairs will qualify a dog that appears primarily black to be called brindle.

The dog above is an example of a mostly black  with little brindle.  Below is a tiger brindle which has many colors stripped through the black. Both are called Brindle with White on the pedigree.

Tiger Brindle

 White with Brindle

White with Brindle or (pie-bald) color refers to a dog that is white with brindle spots. There are also Red Pieds (above right) and Honey/ Lemon and Fawn Pieds.  

  Pieds can have a double hood.....

  or a single hood. 

 Creams and Fawns

Above is a good example of a cream.  Fawns will have a little more gold or beige coloring-see the Black Mask fawn's body color shown above.
