The tortoise shell pattern is naturally occurring in Maew Boran. They come in a variety of shades, some darker and some lighter, they have points, and can have eyes that range from blue to aqua to gold. The Tortie Maew Boran is perhaps one of the most exotic looking of the color varieties, no two cats have the same appearance.  In addition, there are cats that display a wild collection of traits, such as spots and points and blue eyes or tabby patterns with points.

While not all of these colors are described in the Tamra Maew  (Cat Poems), or accepted by western cat associations they are no less colors that are part of a natural breed.
