The solid brown cats I have seen have all been pedigree crosses or pure pedigree
The reason for the confusion with CHARCOAL BENGAL CATS and solid bengal cats, is because some charcoal bengals are almost solid in color. The charcoal silvers and charcoal browns can have a black body with ghost markings, just like a melanistic. The charcoal snows can have a solid color "smoke screen" over the body, like solid snows have.
It has been documented that self-brown cats were known and shown in Europe in the 1890s. One of the names given these cats was "Swiss Mountain Cat." These cats disappeared until the post World War II period, most likely because the Siamese Cat Club of Britain issued a statement around 1920 that, "the club much regrets it is unable to encourage the breeding of any but blue-eyed Siamese." As a result, all solid-brown cats with non-blue eyes were excluded from Siamese classes at shows; and that was the end of brown cats as the early breeders knew them.

I don't think I've ever seen a solid brown cat before.
The jet-black colour you known as "black" is called "ebony" and "ebony tabby" in Orientals, "black" in solid coloured domestic shorthairs, "brown" when it refers to brown tabby domestic shorthairs, "bronze" in Egyptian Maus, "tawny" in Ocicats and "ruddy" in Abyssinians. In colour-pointed cats, "black" is called "seal". In Burmese it is "sable" or "seal sepia" and in American Tonkinese it is "cinnamon" or "natural mink". In the Asian breed (self Burmese cats) it has a breed name to itself "Bombay". Shaded silvers, black smokes and chinchilla cats may look various shades of grey or silver, but they are black cats with silver roots to their fur. Add dilution and it becomes "blue". Modify the dilution and it becomes "caramel". Yet it is still basically a black cat.2.) The second way to tell the difference is that all solids will have either a solid face with no tabby markings, or in the case of solid snows and silver smoke, the markings will be visible but will be smoked over. Sometimes the charcoal browns will get brownish color goggles, but they should not be smoked over with black color like the solid bengal cats have. Charcoal bengals will still have visible Tabby markings on the face, and a light or white belly.Solid Wood Wooden Carved Kitty Cat Kitten Figurine Statue Brown Black 9" BF in Home, Furniture & DIY, Home Decor, Decorative Ornaments & Figures | eBayBut you're right solid brown is pretty rare - tabbys are more common than solid colours anyway, and I think brown may be recessive (cat colour genetics are complicated).
