A Lilac Point Burmese has lilac markings, while the Siamese, called this point, is named for a tasty shade of brown
Selective breeding has reduced the tabby markings to produce a cat that 
looks solid ... gene she will be dilute tortoiseshell (blue/cream, lilac/cream or fawn
/cream) .... A seal-point Siamese may appear to be brown, but genetically it is 
black!
