Yeah, this is going to be a profound post.
Anyway, what got me thinking was how metallic blue the water was. I recently tossed a long lasting cleaning tablet into the reservoir that is supposed to clean the john whenever you flush it. For whatever reason the doo-dad dyes the water blue as well. This is probably to put one in mind of the endless blue of the ocean or a mountain lake. That, and when the color runs out you know it's time to buy a new breath mint for your toilet.
But what if you don't want blue water? I think the cleaner comes in some sort of wintergreen color as well. Neon green water is not exactly a color you see in nature outside of stagnant, algae filled ponds. But why not let the consumer decide on the color of water they want? Why not red? Every time you flush you could thrill to the sight of blood red water seeping out of the fixtures. It would be like a horror movie every time you flush. That would be quite the sight.
