A reader device for identifying a color property in an area of interest and presenting content in response. The reader device comprises a light source unit for emitting a number of monochromatic lights having different wavelength bands toward the area of interest and a single photoelectric sensor for intercepting a reflection of the monochromatic lights from the area of interest, thereby providing the color property output and presenting the content according to the color property.
