Thanks for your replies everyone and I'm sorry I'm slow answering, I have been having trouble getting HC to load on my laptop for the last couple of weeks!
Rads thank you, yes the colours are all a bit bewildering aren't they!
Nancy thank you, I thought she was probably Golden but it's good to have it confirmed and thanks for the pic!
Piebald thank you! I thought she just had a nice glossy coat to start and then I started to see it was quite different to Smokey's.
souffle thank you, well she's quite grey really underneath and down her sides, I think this picture shows her colour quite well - even though the pic looks a little dark, she is pretty much that colour underneath -
