1. A colorimeter comprising:
a colorimetric sensor that performs colorimetry;
a first wireless communicating interface that performs first wireless communication with a terminal device according to a first wireless communication standard, the terminal device being wirelessly connected to the colorimeter;
a second wireless communicating interface that performs second wireless communication with the terminal device according to a second wireless communication standard; and
a processor that controls the first wireless communicating interface and the second wireless communicating interface,
the terminal device setting as a colorimetric mode one of a first colorimetric mode and a second colorimetric mode, the first colorimetric mode and the second colorimetric mode being different from each other in how the colorimetric sensor performs the colorimetry,
the processor determining whether the colorimetric mode set by the terminal device is the first colorimetric mode or the second colorimetric mode,
upon determining that the colorimetric mode set by the terminal device is the first colorimetric mode, the processor transmitting, by the first wireless communication, to the terminal device colorimetric data acquired by the colorimetry performed in the first colorimetric mode, and
upon determining that the colorimetric mode set by the terminal device is the second colorimetric mode, the processor transmitting, by the second wireless communication, to the terminal device colorimetric data acquired by the colorimetry performed in the second colorimetric mode.
