A C.I. Pigment Yellow 74 as an insoluble azo pigment is provided. This C.I. Pigment Yellow 74 is crystalline particles. The ratio (26.6°/11.7°) of a diffraction intensity of a peak at 26.6° to a diffraction intensity of a peak at 11.7° in terms of Bragg angle (2θ±0.2°) as measured by powder X-ray diffraction using CuK α-radiation is 0.85 to 1.12, and the average primary particle size is 20 to 130 nm. The use of this C.I. Pigment Yellow 74 as a colorant in a coloring composition enables to provide the coloring composition with excellent dispersibility and good particle size stability and storage stability compared with conventional pigments. The use of this coloring composition enables the formation (recording) of images having excellent clarity and transparency of such high levels that have not been achievable by conventional technologies.

The object of the invention is to provide a CCM calculating system being relatively inexpensive and alleviating the necessity of a spectrophotometer, a CCM calculating method and a recording medium. A CCM calculating system according to the invention calculates a blending ratio of colorants based on stored color data 16. The system has an input device 5 (20b) for inputting data of color specification values corresponding to a desired target color; and a data operation unit 1 (20c) for calculating a blending ratio of colorants for reproducing the target color, based on the input data of color specification values and stored color data. Since the blending ratio of colorants for reproducing the desired target color may be calculated based on the input color specification value data and stored color data, such CCM calculation may be performed without the necessity of a spectrophotometer.
