Shih tzu liver or champagne

When I first brought Maddie home, she had dark brown fur.  As she grew and got older, her fur changed from brown to a milky brown.  My breeder said that her fur color was "liver".  It wasn't until Xmas when other people saw Maddie that they said she looked more like champagne.  So instead of saying I have a liver Shih Tzu, I now can say she's a Champagne Shih Tzu.  Even dogs have problems with hair color...go figure!!!
