This study was designed to investigate the effects of colour in EEG signals as the subjects perceive different shades of colours. Color impairment may make it difficult or impossible for a person to engage in certain occupations. Drivers having color impairment may not be able to recognize the different traffic signals lights which may lead to severe accidents those questions the security of other road users. Persons with colour blindness may be legally or practically barred from occupations in which colour perception is an essential part of the job, or in which color perception is important for safety. Different shades of fundamental colours (Red, Green, Blue) were shown in randomized manner. The various colours show various effects in the energy band of the signal. Based on the data obtained from the experiment, we analyse the brain responses which come from color stimuli. The result gives us a measure to estimate the color stimulus
