I think I would go either with the flesh coloured or very sheer and fairly shiney black tights. There's a website that sells only tights if you want any ideas for tights with patterns etc on. You never know, you may find your dream pair. www.mytights.com
It depends if your shoes show your toes. If they are open toe, definately get some Rimmel sun shimmer - its a God send! You can get it from Boots. If you are likely to get cold, and your shoes are closed toe, then I would say some sheer black tights. Have fun!
