Convert harm into benefit (blessing in disguise)

I can't say the act of peeing is a harm, unless you count the time we waste going to the bathroom. While there has been many distracting things you can do while answering the call of nature, this one takes the (urinal) cake.

Which is a clever idea, as anyone who's been to a male toilet with an "aged" urinal will definitely prefer such vibrant colors over yellow-ish stains. By applying thermochromic paint onto such a mundane item, whoever that did this has certainly converted what is normally a harm into a benefit (TRIZ inventive principle 22).
