Looking for the perfect name for my puppy?

Around Christmas time, I will be bringing home a female Great Dane puppy. I have been leaning towards the name Yue (pronounced Yoo - Aye) which means "Moon" in Chinese, however, a few people think I'm saying, U. A. and that she is named for the University of Arkansas...I don't like that very much. I already had a dog named Luna, so I don't feel right about using it again. But I have a strong affinity for names that mean "moon". Or something that has to do with the sky. She is a Blue Merle, so the color blue is also nice. Any name suggestions? I work for a doggy daycare, so it's difficult to find names that haven't been used before.
