She has beautiful coloring. I believe she is a Tabby as she has the destinctive M on her forhead.
Io's color is Brown Mackeral Patched Tabby, or sometimes called a Brown Mackeral Torbie. She has the tortoishell patching mingled in with the brown mackeral tabby markings. The mackeral pattern is named after the striped mackeral fish, compared to the classic or blotched tabby (with bulls-eye and rings on the side) which is a less common pattern as it is recessive. She's a beautiful girl and looove her poofy tail!
