The Ives Medal Address consisted mostly of demonstrations of phenomena of color perception. The following demonstrations were attempted: blue arcs of the retina, Maxwell’s spot shown with Miles filter (macular pigment as an entoptic phenomenon), attributes of color perception (Desert Island experiment with Priest charts), color perceptions of protanopes and deuteranopes, metamerism (Stearns textiles, Granville grays), chromatic adaptation (simultaneous and successive contrast), and color rendition of light sources (object-color perception as the projection of the after-image of the background onto the object).
