Is it normal that the thought of coloring hair makes me have to pee?

So, ever since I was a kid, I've had this thing where seeing a before/after photo where someone has colored his or her hair makes me need to pee. It's usually dramatic color changes that have the greatest effect, but any noticeable difference in hair color makes me get the urge to go. To some extent dramatically different hair cuts (like superlong hair to a pixie cut) also have this effect. I don't like or dislike coloring hair or changing it; I myself have made some dramatic cuts (but never colored it, as I've been afraid I'll pee in the stylist's chair).
It's not that it makes me squeamish or something, I just get a huge need to pee.
As a matter of fact, writing this whole thing has made me need to pee even more. It really bothers me; I feel like I am completely abnormal. After a while, the effect will wear off and I will no longer need to urinate, but for about five minutes after I see the picture or video or even THINK about it, that's when I have to go. It's not like I can't hold my pee...usually I just ignore the urge and wait for it to go away.
So, is it normal?

    It's because the bilirubin count in urine is directly attributable to the contrast of the faces we see at the time we feel like peeing.

    Or maybe I made that up. Weee! I've had two pints of chocolate milkshake and I'm giddy. Where's devilla? I want to play!
