ABSTRACT:
A color image processing apparatus for converting a predetermined color in color image data into data of desired characteristic extracts density information and hue information with respect to the color image data. Density information and hue information in respect to a predetermined color are set. Judgement is conducted as to whether a first difference between the density information of the color image data and the density information of the predetermined color falls within a first predetermined range and also as to whether a second difference between the hue information of the color image data and the hue information of the predetermined color falls within a second predetermined range. The color image data is converted into the predetermined color on condition that the first and second differences fall within the first and second predetermined ranges, respectively.
