I need some ideas to make my tack purple...?

So, I am going to a show this weekend, and it is in remembrance of a young girl who died while riding. Her favourite colour was purple, so we are supposed to wear purple, and use our purple tack if we have any. Unfortunately, my horse's colour is blue, so I mostly have blue stuff. I have a purple saddle pad and halter, but that's about it. I was thinking about putting purple vet wrap over my horse's boots and possibly braiding my horse's mane with purple ribbon, but what else could I do? It's a barrel show, so it doesn't have to be fancy or anything.
