A non-attended event related potential brain-computer interface method for color sensation automatic identification, comprising the following steps: (1) connecting an event related potential processing device to an amplifier for detecting an electroencephalogram signal and to a multi-lead electrode cap; (2) configuring color stimulus parameters of a color stimulus image for a user in the event related potential processing device; (3) subjecting the user to acoustic stimulation at the same time as he or she is subjected to color stimulation; (4) acquiring an original electroencephalogram signal of a non-attended event related potential of the user during the aforementioned process; (5) and using the event related potential processing device to process and analyze the original electroencephalogram signal, thereby acquiring time sequence specific components generated by different color sense sequence stimulations, and establishing the non-attended event related potential brain computer interface for color sensation automatic identification according to said specific components. The non-attended event related potential brain-computer interface for color sensation automatic identification provides a new technical means for brain-computer interaction in color sensation automatic identification and an objective color sensation detection function, thus overcoming the defect of requiring the subjective cooperation of a user.
