PROBLEM TO BE SOLVED: To provide a color toner kit using a yellow toner, a cyan toner, a magenta toner and a black toner, and capable of ensuring the color tones (color reproduction range) of process inks. SOLUTION: In the color toner kit, the yellow toner in which, in a spectral- distribution diagram in which the reflectance (%) is plotted as ordinate and the wavelength (nm) as abscissa, the reflectance determined for the toner in a state of powder ranges from 15% to 20% at a wavelength of 500 nm, and ranges from 75% to 80% at a wavelength of 600 nm, the cyan toner in which, in the like spectral-distribution diagram, the reflectance determined for a toner in a state of powder ranges from 30% to 35% at a wavelength of 450 nm and ranges from 35% to 40% at a wavelength of 475 nm, and the magenta toner in which, in the like spectral-distribution diagram, the reflectance determined for a toner in a state of powder ranges from 5% to 10% at a wavelength of 425 nm and ranges from 65% to 70% at a wavelength of 675 nm.
