[Lady of Yorkies]

Ok, if this theory is true where does that leave a dog who on one day has red reflections and the next green reflections? Lady is 17 1/2 months old. On Thursday I took the first picture and you can see her reflection is definately red. The second pic was taken the next day, Friday, here the color is a little more difficult to see but it is definately not red. It does appear to be more gold with some green peeking thru and I'm not sure this is the right photo, but there is one where her reflection is definately green. So what does that mean? Sylvia
