In this paper investigation of color vision geometry in the human eye is presented. The human eye has two types of photoreceptor cells called rod and cone-like cells. These two types of cells in the human visual play different roles. Cone-like cells lie at the center of the light-sensitive area of the eye, known as Fovea, allow human eye to the color vision. The cylindrical cells with high sensitivity to light intensity can detect dim environments but are not sensitive to the color. They lie on the edge of the light-sensitive area of the eyes. Studies show that in looking at a color object rather than black and white structure, the center of human vision is more colorful than the side area. In this paper, a new color pattern was designed and a significant number of it was reproduced on a page. The plan is shown to different people. In this work the results of color or black and white diagnosis in the central point of vision and in adjacent areas, at first sight, and after informing people about the content of the test, are presented.
