When using a light sensor, you are able to use red color-filter, placed in front of a light sensor, to detect red light only.

Colors filters will filter the colors of incoming light, making it so only red light would be visible to the light sensor.

A color filter would probably be sold separately from a light sensor, although you could probably do some shopping around to find cheap examples.
