1. An apparatus for detecting the presence of a color dye in a water sample, comprising:
- a) a light source to generate a light that passes through the water sample;
b) a color sensor to measure the light that has passed through the water sample by generating at least a first color signal and a second color signal based on the received light; and
c) a dye detection mechanism coupled to the color sensor to receive the color signals and to determine whether the dye color is present in the water sample based on the color signals.

Abstract
Method and apparatus for detecting the presence of a color dye in a water sample are described. Light is generated and passed through a water sample. A color sensor is utilized to measure the light that passes through the water sample. Based on the measured light, it is determined whether a dye color is present in the water sample.
