Embodiments of the present invention disclose a method and a device of testing color blindness, which belong to the technical field of test. The method includes: acquiring a plurality of preset coloring schemes, each of which is provided to test one type of color blindness and comprises a base color and a changing color acquiring color sense test patterns, each of which corresponding to one of the coloring schemes changing a color of at least a part of the grids in one of color sense test patterns one by one from the base color to the changing color according to the grid color-changing sequence of the corresponding color sense test pattern during displaying the corresponding color sense test pattern, when the corresponding color sense test pattern is used to perform color blindness test on a tested person, and acquiring positions of the eyeballs of the tested person as the color of the grids is changing obtaining a first fitting degree by fitting an acquired movement trace of the color point to a movement trace of the eyeballs and, judging which type of color blindness of the tested person is according to the first fitting degree. According to the present invention, dependence analysis is performed on the movement trace of the eyeballs of the tested person and the movement trace of a color point in the corresponding color sense test pattern to obtain in quantitative sense which type of the color blindness of the tested person is, thereby increasing accuracy of the color blindness testing.
