On Vision and Colors from a prism, however, the production of white can be demonstrated by using a mixture of colored light from each of the three main pairs of complementary colors: red – green, orange – blue, or yellow – violet. White can be produced from two complementary opposite colors when both of the external causes of the colors excite the same retinal place at the same time. Newton claimed that white could be produced by the aggregation of his seven prismatic colors. He erroneously considered color to be in light instead of in the eye. White is the result of the combination
Venous translucence tonality with the change in source direction. A shade with the change of source direction arises. It is known that the refraction index changes in agreement with the spectrum of transmitted light; when the white light is projected and finds an obstacle, it becomes separated into the three elementary colors (red, blue and green). Light during translumination may have greater dispersion or reflection, depending on how the source is placed on the examined area. This handling may improve or degrade the image, depending on the examiner's experience. Skin is opaque to light. In physics light reception, heat or other type
