My Siamese had a beautiful dark brown velvet nose that changed overnight to pink ! She is now four years old and is pictured with her "sister", a blue Burmese. The Siamese coloring never changed to tortie, she just has speckles on her ears, eyes and mouth. No one has offered any ideas as to why? :) She is quite the team with her "sister". Where one goes, the other follows. Vet visits are always in tandem, regardless of reason. The burmese girl is 5 years old. They are the best friends and their personalities really complement each other. Burmese girl is patient and calm and of course the Siamese girl is hyper and easily startled. They are a blast together.
