Ladies I need advice for a date! Is a pink rose a good idea?

I'm going on my 5th date with this girl and I want to bring her a single rose. I don't want to bring a red one, because thats generally seen as being in love. I really like this girl and think shes beautiful and really sweet. Is a single pink rose a good idea? I got her a mixed bouquet for the 3rd date and she was really surprised. I want to step it up a notch and make her smile when I pick her up for dinner this week and show her that I care about her.
