A line sensor is a little device used to detect difference in color by bouncing back light on a surface; the darker the surface the less light bounced back and vice-versa. The way this works is as the light bounces back the detector receives light and creates a little current which sends it to the cortex, then the brain reads the values and determines what the surface is.
The color sensor works in a similar manner. Instead of detecting a specific color, shine a specific color on the object and report what shines back the brightest. When you shine lights on an object, it absorbs colors indifferent from it and reflects more of the same color shone on it.
