A pattern extracting apparatus extracts a pattern of a desired color from an object containing a plurality of color patterns. In the apparatus, the object is irradiated by light to provide data relating to color components and the data relating to color components are converted into Munsell color data H (Hue), V (Value) and C (Chroma). After that, a pattern of a specific color is extracted from the object based on the Munsell color data.
