Sharingan

Can I please use this? I'm writing a story on about a girl(me XD) who belonged to a clan who were allies to the uchihas and she ,her brother (dead) and her great great grandmother (also dead) were the only ones who knew it. I've been searching all over for someone who did this. This is really great, but her eyes are a very bright and rare blue ( a bit like ino's but lighter). I promise to give credit in my book to you! tnx for reading!
