Interaction of color by Josef Albers notes in the introduction area of his book that in order to use color effectively it is necessary to recognize that color deceives continually. First, we should know that the same color evokes innumerable readings. Instead of using the laws and rules of color harmony we should recognize the distinct color effects are produced through the interaction of color- for instance 2 very different colors look alike or nearly alike.
So the aim is to develop experience for an eye for color. This means seeing color action as well as feeling color relatedness, developing observations and articulation and practice before theory.
Practical exercises in the book show color relativity and instability through color illusion. It helps to visually realize the interaction between color and color to an interdependence of color with form and placement.
