Lilly is definitely a "colorpoint." This is easily determined by the fact that on her legs and head (I can't really see much tail in any of the pictures shown) she has very clear tabby markings and on her body it is a very washed out color with no tabby markings visible. She could be "pointed" or "mink" it is hard to tell many times, both "pointed" and "mink" are forms of the colorpoint genetic expression. There are three forms of the "colorpoint" gene, and three types of colorpointed coats (pointed, sepia, and mink), but read on please.
The first and most common type of gene is the non-colorpoint gene (we will call it C, apologies to Gloria Stephens), this gene causes a cat to have normal (no colorpoints) and is dominant; so if a cat has just one copy of this gene it will be a full color cat, this is the gene that all non pointed cats express. The second gene mutation is the pointed gene (let's call it c(s)), this gene causes the color to be extremely washed out on the torso (where the cat is the hottest), almost, but not quite white. You have to have two copies of this gene to be a "pointed" cat as it is recessive, examples of cats that are pointed are Siamese and Himalayan. Note that often Siamese and Himalayan are often of varying shades on their torsos, darkening often occurs with age (as the cat's circulation grows poorer), but not neccessarily. The third gene is the sepia gene (c(b)). This gene is similar in action to the pointed gene, but less so. Again it is recessive, so you need to copies to be "sepia." The sterotype example of this colorform is the Burmese (American), the color is only very slightly washed out on the torso. If you mix the sepia and pointed genes you get the third type of colorpoints: mink. Mink cats show washed out color on the torso less than pointed cats but more than sepia cats, the classic example here is the Tonkinese. Note that color point genes can be mixed with white spotting genes (example: Birman), the two are completely separate. Also you can have cats with tortie points or torbie (tortie tabby) points as well as solid and lynx points. Any cat with washed out color on the hotter areas of the cat (mainly the torso) is expressing the colorpoint genes. Also note that the piebald white spotting gene generally starts at the paws and works up from there (black cats occasionally show white chest lockets), so white spotted cats almost invariably have white feet.
