Tabbies may be brown, grey, orange, or calico, including dilute versions of these colors. The most common tabby color is brown. All orange cats are tabbies, and the orange portion of calico cats will always show tabby patterns. Since the orange gene is on the X chromosome, about 80% of orange tabby cats are male, and nearly all calico cats are female. Colorpoint cats (Siamese, Himalayan, etc) that are tabbies are referred to as lynx point. As with solid-color cats, tabbies may also be partly white, such as tuxedo or van patterns. The tabby pattern is not visible at all in the white portion.
