Low chlorine colors are very difficult to read. It might help if you use it for higher concentrations, but I've had trouble figuring out how much chlorine and chloramine is in my drinking water. I have readings, but my score is a fairly wide range of colors. A little disappointing. On the other hand, it was at least a cheap experiment and the color change showed that the vitamin C water filter I bought for the shower was at least doing something.
