L.2013.6.4 d: The Meeting, plate 4 from Revolving Doors

IV. The Meeting: Three beings meeting in one plane are contrasted, a yellow concave, a red convex, and a spiral blue. There is mutual affection of color over the areas that two or three occupy together, resulting in a modification of their color but not in their form. Still it is possible to see the areas held in common as distinct additions. As in the other scenes the lines form a not too literal boundary for the planes.
