Abstract: Difficulty recognizing colors which a sight-impaired person has is solved by a color identifying device of the invention comprising a means for identifying a color by comparing data measured by color sensor 4a and stored reference data and a means for externally outputting the color identified by the color identifying means by a voice, wherein a measurement aperture portion is pressed against the surface of an object the color name of which a sight-impaired person desires to know, light (of three RGB types) reflected from the object is measured by the measurement portion 4, the measured data is transmitted to the color identifying means, the program within the color identifying means calculates the measured data and compares the calculated data with the reference data (table data) which is systematically classified, the color name of the measured data is selected, and the color name (the basic color name, lightness, chroma and hue) of the object is outputted from speaker 28 by a voice.
