While the idea of a shower head changing colors in response to a change in water temperature sounds kind of amusing, we think people ought to consider installing a shower head that will improve the quality of their shower water rather than the lighting in their shower stall.
Again, we find the following ‘technology’ rather cool… but somewhat superficial in the grand scheme of things.
You got your skin burned in the hot shower due to a mistake of turning up the temperature control too high as you couldn’t see the reading on the control knob clearly. So, you’ll need a better gadget that would tell you in a more prominent way that the water is burning hot. Here comes a color changing illuminated shower head, which changes color according to the temperature of the water. When you’re increasing the temperature of the water, the color will change from white when it’s cold, to blue, then purple and finally the hot red.
The color changing illuminated shower head features a temperature-sensitive color-changing LED. The shower head needs neither battery nor external power to run. All it depends is the water that runs through it. Installation is easy, just unscrew your current shower head and screw this one on. ( source )
Really cool looking shower colors may do a lot to set the mood for some things, like, um… Well, never mind that. Let’s just focus on the idea that shower heads designed to remove chlorine, excessive water hardness, or other water impurities make a lot of sense.
