This memo-game is based on a very special concept: the colors follow the format used in Johannes Itten’s color theory: red for a square, blue for a circle, yellow for a triangle, orange for a trapezium, green for a spherical triangle, and purple for an ellipse. The colors are shown with the corresponding form, which increases their specific impression.

Furthermore, each color is present in six different nuances; this increases the perception of the color tones and supports the creative process of finding new names to specify the individual forms. As the cards are turned over new color contrasts are revealed; these can also be used to intensify knowledge of color theory. Thus, these cards must not just be used for playing the memo-game, they can also be used for inspiration and for experimenting with different color combinations, series and tones.
