The cheap solution would be to use different colored light filters on an array of photovoltaic cells.

You would need an optical sensor like a photo transistor and a color filter to let the sensor "see" only the light you ant to detect. If you want to detect more than one color, you would need multiple sensors and filters or filters that can switch in and out.
