Claim:
1. A color measurement device, comprising: a spectrometer that disperses light from a measurement target, wherein the measurement target includes a color patch and a reference color region, the reference color region includes a first position and a second position, the color patch is positioned between the first position and the second position, and the first position, the color patch, and the second position are disposed along a predetermined direction; a movement mechanism that moves the spectrometer relative to the measurement target; and a control device that controls operations of the spectrometer and the movement mechanism, wherein: the spectrometer is operable by the control device to carry out spectral measurement for each of the first position and the second position, and acquires measured values, the control device determines a reference value corresponding to a color measurement position that is a position in which the color patch is disposed based on the measured values at the first position and the second position, and the control device determines a color measurement result of the color patch based on the measured values that are acquired when the spectrometer carries out the spectral measurement at the color measurement position and the reference value.
